Ligeti’s Hamburg Concerto as a Summary of Late Artistic Tendencies Valeriya Zharkova, Oleksandr Zharkov, Olena Antonova, Tetiana Filatova, Ganna Rizaieva Ukrainian National Tchaikovsky Academy of Music, Ukraine Submitted: 2023-07-14. Revised: 2023-08-05. Accepted: 2023-10-05 Abstract The relevance of this study is conditioned upon the need to highlight the internal content of the modern academic musical language and, specifically, the features of the late work of G. Ligeti. This paper aimed to conduct an in-depth study, comprehensively covering, analyzing, and gen- eralizing the panoramic display of the creative traditions of G. Ligeti in the context of world musical art. The materials of this paper are sources that illuminate the path of stylistic search and the evolution of the musician’s composition, as well as information about the leading directions of the modern world academic musical environment. The research methods included a search and collection of information base dedicated to the Hamburg Concerto by G. Ligeti; analysis and compilation of available materials; determination of the leading categories of the phenomenon presented in the late period of the composer’s work; showing his stylistic and compositional prin- ciples as a single multifaceted system. The result of the study was the individual author’s concept of vision of the role, significance, and content of G. Ligeti’s work in the history of academic musi- cal art. The practical significance of this study was manifested in the demand for the results of this study among students of secondary and higher musical educational institutions, as well as among specialists investigating the processes of transformation and expansion of the boundaries of the melodic, compositional, and technical arsenal of professional musical creativity.

However, all the INTRODUCTION The problem of summarizing the late tendencies of G. Ligeti’s work on the example of his Hamburg Concerto requi- res its study due to several factors. One of them is the need to reveal the voluminous, modernized, and complicated musical lan- guage of academic music, which was for- med by the end of the 20th - and beginning of the 21st centuries, and the context in Corresponding author: E-mail: valeriya.zharkova@ukr.net p-ISSN 2541-1683|e-ISSN 2541-2426 Harmonia: Journal of Arts Research and Education 23 (2) (2023): 333-345334 listed components have not yet been ana- lyzed as elements of a single composite system. Scientists from different countries fo- cused their attention on its various aspects. Thus, A. Bauer (2020) notes that the legacy of the composer combines intellectual so- phistication with respect for the sensual at- tributes of his musical themes. Much of the research related to the music of the Hunga- rian composer revolves around categories such as musical technique, theoretical wri- tings, and lectures. Specialist (Bauer, 2020) states that for six decades, the musician has been creating solo chamber works, choral compositions, experimental opu- ses (Fluxus), electronic, orchestral works, and examples of various genres of musical theatre. His early orchestral compositions, Apparitions (1958–1959) and Atmosphères (1961) cemented Ligeti’s reputation among the European avant-garde. The scope of his style expanded significantly during the 1970s by turning to polar genres: intimate solo works for harpsichord and the gran- diose opera The Great Death (1974–1977, a new edition appeared in 1996) (Bauer, 2020). Elements of musical traditions outsi- de of Europe and, specifically, African art, as well as the canonical Music of Conlon Nancarrow and fractal geometry, enriched in the 1980s the fund of his intonational language and stylistic system based on the native national language and the traditions of the academic atmosphere, in the field of which G. Ligeti was at the dawn of his cre- ative career (Bauer, 2020; Voyvoda, 2022). M. Chemillier (2020) plunges into the study of the updated interpretation of sound in the Music of G. Ligeti, as a weigh- ty unit that includes many mobile compo- nents. In his opinion (Chemillier, 2020), the transformation of sound is based on such methods as changing the pitch and its modification in time. In this case, the sound acts both separately, individually, and in the context of a harmonic complex or micropolyphonic construction (Chemil- lier, 2020). I. Pace explores the issues of the emergence of a renewed sound field both through the modernization of intonatio- nal and technical (interpretative) aspects: meter and rhythm, as well as musical no- tation, accentuation on the example of G. Ligeti’s Etudes for Piano. He thoroughly examines the principle of touching the pia- no keyboard, special techniques for using the pedal, and the effects of discontinuity and continuity in the sound of a horizontal musical-thematic line (Pace, 2012). A. Bauer (2019) is absorbed in the study of ideological content, which is contained in the images of the musician’s works. According to his concept (Bauer, 2019), the Hungarian composer manifests himself in his own works (“Etudes for Pia- no”) as an ideological architect, a symbol of the era of late modernism, where virtu- osity in performance is interpreted broad- ly and polarly: from rejecting its necessi- ty and prevailing, to doubling the effects from the use of its resources. A deep philosophical study of G. Ligeti’s work is carried out by E. Schrei- ber (2019). The scientist (Schreiber, 2019) analyses the comments of the Hungarian composer on his own works of different periods, which helps reveal the creati- ve evolution of the musician more subtly and clearly. Specifically, it is noted that in the early stages, Ligeti purposefully emphasized the analytical and interpreti- ve aspects of his works, to which he con- sistently returned later (Schreiber, 2019). The musician’s appearance as an original artist was clearly manifested in his retros- pectives at the turn of the 1950s and 1960s. (Schreiber, 2019; Hromchenko, 2022). Since the problem of an individual creative style and the use of a wide range of compositional techniques of a musician is voluminous and multi-vector, it requires its study, illumination, and conceptualiza- tion, where it will be presented as an in- tegral complex system. To accomplish this task, this publication turns to the materials available in musicology that address this issue; new sources are discovered, and the collected information is analysed; the pro- cesses of interpretation of the Hamburg Concerto are monitored. Valeriya Zharkova et al., G. Ligeti’s Hamburg Concerto as a Summary of Late Artistic Ten- 335 METHOD The materials of this study included sources investigating several large-scale blocks. The first of them analyses the in- tonational and compositional-technical fund of academic music of the late 20th and early 21st centuries. The second block covers the characteristics of the work of the Hungarian composer. The third block is devoted to extensive coverage of the con- tent, significance, and role of the Hamburg Concerto both in the context of G. Ligeti’s life and professional path and in the world of composer practice. Thus, the information provided by the spheres of musicology, orchestration, and performance practice was used. The data of scientific analysis of the methods of creating music were studied. Among them, it is necessary to name such elements as melody and rhythm, thematic mode, timbre, dramaturgy, and genre structure. They were applied when correlating G. Ligeti’s style and the objective processes of complicating the musical language, expan- ding the forms of its current presentation. The study analyzed the sources co- vering the transformation of the Hungari- an musician’s work, which is reflected in the updated, individualized interpretation of several components of composer prac- tice. These include instruments that have both tempered and untampered tunings semitone divided into microparticles. The aforementioned information was put into practice when compiling a panorama of the Hungarian composer’s artistic labora- tory, within which the Hamburg Concerto arose. The publication covered materials directly analyzing the Hamburg Concerto. They were taken from studies in musico- logy, history, music theory, and musical pedagogy, specifically, the methodology for performing works by contemporary composers. They highlight the list of com- posers’ writing techniques used in this stu- dy: transformation of folk-national origins and genres (folklore, academic). They were used in defining and deriving the leading categories of the Hungarian composer’s musical thinking. Among the research methods for the problem of summarizing the late trends in G. Ligeti’s work, using the example of the Hamburg Concerto, it is necessary to name scientific and exploratory, analytical, sys- temic, ideological, and thesis. The first of them is based on the search and collecti- on of sources on the subject under study. The second aims to study and complete the received base of materials. The third method aims to identify and deduce the categories that form the basis of the crea- tive style in the Hamburg Concerto. The fourth is responsible for creating an indi- vidual author’s concept of a phenomenon that embodies the problem under study in the form of a complex, multifaceted, and holistic system. The first stage in the development of a topic dedicated to modern academic mu- sic, the work of G. Ligeti and his Hamburg Concerto was carried out using a scienti- fic exploratory method, the foundation of which is the search and collection of infor- mation. On its basis, a database of sources on the research topic was created. The second stage of investigating the problem was the use of the analytical method of its scientific development. It in- cluded analysis and compilation of materi- als of the obtained information base. This stage became a prerequisite for the disco- very of significant elements of the system of creative approach to the creation of the Hamburg Concerto. The third stage summarized the tendencies of G. Ligeti’s late work on the example of the Hamburg Concerto using the systematic method, the essence of which is to find and outline the leading ca- tegories of style in general and the compo- sitional features inherent in the Hamburg Concerto. The fourth (final) stage of the study was based on the implementation of the ideological and thesis method, which be- came the basis for the formation of an in- dividual author’s concept regarding the vision of the discoveries of the Hamburg Harmonia: Journal of Arts Research and Education 23 (2) (2023): 333-345336 Concerto as a single complex system. This method of creating an original concept contributed to the implementation of no- velty and prospects, which are contained in the content of the publication. RESULTS AND DISCUSSION When summarizing the tendencies of G. Ligeti’s late works on the example of the Hamburg Concerto, a complex, volumino- us, and integral system of compositional- technical, stylistic, rhythmic, intonational, and timbre components of his writing was identified and outlined. Each of them, as evidenced by the data of the present study, differs in a certain scale and function. Table 1 lists the categories, as well as their characteristics, which are inherent in the composer’s style of writing. Table 1. The main creative principles of G. Ligeti and their description Focus- ing on the instru- mental concerto genre Attraction to a large concert form, which provides unlimited opportuni- ties for compositional experiments in the field of the formation of thematics; intonation and rhythmic structure; timbre and textural dramaturgy, as well as the structural aspect Mod- erniza- tion of the instru- mental concerto Implementation of artistic compo- sitional and technical means that provide a new vision of musical mate- rial, its main themes and episodes of development, dynamics, as well as an individual, unprecedented interpreta- tion of expressive techniques that exist in the practice of creating music Synthe- sis of academ- ic and folklore tradi- tions The principle of referring to com- positional structures and writing techniques developed by the academic practice of creating music over several centuries, including ultramodern techniques for designing and devel- oping material in a harmonious and direct combination with elements of folk genres (specifically, interval and metro-rhythmic micromodes, natural tunings) Appli- cation of avant- garde style The introduction into the genre of in- strumental concerto of such categories as microtonality, sonorous vertical, micropolyphony Com- bina- tion of modern complex writing tech- niques and neo-ro- mantic style el- ements The desire for a natural and profound combination of the latest composi- tional and technical fund of the late 20th – early 21st centuries and the integral components of the style of the Romantic era in music (specifically, solo instruments, the national folklore- genre basis in the form of imitation of certain rhythms and timbres, as well as a characteristic genre and the structur- al aspect of the major concerto form) Source: created by the authors of this study. Thus, Ligeti’s creative heritage inclu- des seven instrumental concertos, and this is more than he has written in any other musical genre. The method of end-to-end development of motive groups (cells), in- herent in this large-scale form, is being implemented. Each of the seven concertos has a unique stylistic, structural (a departure from the traditional three-part form), and timbre-instrumental appearance, reflec- ting the author’s tortuous trajectory of the author’s creative searches. Specifically, he created double (Concerto for flute and oboe with orchestra), ensemble (Chamber concerto for 13 instruments), and orchest- ral (Concert românesc) concertos. The first Concert românesc (1951) chronologically records the impressions of studying folk music at the Institute of Folklore in Bucharest. Three concertos, cre- ated in the 1960s and early 1970s, capture avant-garde experiments associated with the ideas of sound-colourfulness, micro- polyphony, and static composition. The last three instrumental concertos, dated 1988 and 1999, demonstrate the interaction of the full range of previously developed writing techniques with neo-romantic ten- dencies, indicative of the late period of the musician’s work. The ways of formation and development of the composer’s works are presented in Table 2. Valeriya Zharkova et al., G. Ligeti’s Hamburg Concerto as a Summary of Late Artistic Ten- 337 Table 2.

The nature of the images and themes of the Hamburg Concerto, its genre, and structural foundations, as well as a set of compositional and technical means, form an integral system. It includes such blocks as the thematic modus (sonoristic field; me- lody in the form of an individual horizontal line; intonational, timbre, and rhythmic re- sonation); dynamic principles (variability; comparison of modal elements and scales in different pitch contexts; micropolypho- ny); timbre architecture; interpretation of national traditions combined with modern writing techniques. Figure 1 illustrates the structure of G. Ligeti’s musical language used in the Hamburg Concerto. Blocks are given that form its basis and at the same time realize the composer’s creative sear- ches, his experiments in the field of app- lying various techniques and their combi- nations. Figure 1. G. Ligeti’s Hamburg Concerto as an indicator of the modern musical language system Thematic material (mode), in combi- nation with dynamic principles, features of timbre design, and rhythmic schemes, con- centrates a certain type of presentation of musical thought. When analysing each of the parts of the Hamburg Concerto, their Harmonia: Journal of Arts Research and Education 23 (2) (2023): 333-345338 different variants were identified. Thus, the First Movement – Praelu- dium – opens with the composer’s classic, textbook technique: a microcluster of E- flat - F for natural horns, which then ex- pands to a fifth of D-flat - A-flat. Against its background, the soloist sets out a rat- her lengthy “frozen” melody. In measure 10, the middle section begins, built on the soloist’s wide expressive leaps, with the support and doubling of the French horns and the sonorous clusters of other instru- ments. In sharp contrast in measure 15, the last section breaks in, built on a unison and cluster line for the strings, which are chanted by all instruments, and the effect of declamation is enhanced by micropo- lyphonic imitations on woodwinds and brass instruments. The Second Movement consists of three sections – Signale, Tanz, Choral. Its beginning is a spectacular dialogue bet- ween the soloist and the horn ensemble, built on a fanfare takeoff along two minor and two major thirds. The horns echo the solo instrument. The middle section is a dance representing a three-part, with the soloist’s stepwise movement of the melody doubled within the interval of a quart of one of the horns (fourth), which creates a special sound effect. At the same time, the second and third horns, in a Cancrizans imitation, set out the intonations of the ini- tial fanfare, thanks to which both sections are combined. Such a vertical alignment is indicative of Ligeti. Doubling to a fourth creates a sonoristic effect, on which comp- lex imitation is superimposed by counter- point. The beginning of the third (lyrical in figurative structure) section – the Choral – sounds muffled by four horns, and the abundance of natural overtones gives it a specific sound. Like the First Movement, the Second Movement ends with an exten- ded sonorous layer for wood and stringed instruments. The Third Movement has three small sections: Aria, Aksak, Hoketus. The first of them is a soulful Aria, the melody of which is heard by the soloist. It is supported by soft string chords, built as a combination of two fifths: B-flat - F and C - G, in combi- nation with which the interval of a second B-flat - C is observed. The colorful effect is enhanced by the individual phrases of the four bongs. If we talk about the melo- dy in the soloist’s part, then it first builds up as a varied movement along the scale of E-flat - F - A-flat - A - B - C, which also hearkens back to the First Movement. In monophony, the sonorous effect is created by the fact that the sounds of E-flat - A-flat - A should be played by the performer as natural, untampered. The second section is Aksak, a me- dieval dance performed in the countries of the Balkan Peninsula, in Hungary. In this case, Ligeti takes his rhythmic basis and organization of durations: 4 + 3 + 2. The composer builds the horizontal line in pa- rallel fifths, colorfully, from the perspective of timbres, embodying it in the orchestral fabric. The beginning of the second section is distinguished by its relief: the G-D fifth is played, where the lower sound is per- formed by the bassoon and the upper one – by two flutes. This figure is doubled by a marimba, which is joined by a fifth for bas- set horns and a fifth pizzicato for strings. The counterpoint to this melodic line is played by separate phrases- echoes from the horns, creating continuity with the first and second sections of the cycle. The third section – Hoketus (measu- re 24) – synthesizes the intonations of Ak- sak, melodic turns from the Aria and some linear moves that refer the listeners to the material of the end of the Prelude. In this case, Hoketus is a natural continuation of the dance, but with maximum polyphonic complication and the combination of va- rious layers that do not coincide in metric terms, creating the illusion of aleatorics. In this case, the composer interprets Hoketus as a technique in the context of a complex orchestral texture. The Fourth Movement consists of four sections: Solo, Intermezzo, Mixtur, Kanon. The first section – the horn solo – creates an intonation and genre arc to the first section of the third movement (Aria). The melody is built as a free movement of Valeriya Zharkova et al., G. Ligeti’s Hamburg Concerto as a Summary of Late Artistic Ten- 339 material, with an abundance of expressive jumps and soft progressive moves. As in the previous movements, the soloist’s part retains the imitation of natural horns and implements the techniques of micro dyna- mics. The sound of a horn with a mute cre- ates the updated timbre colouration. Here, the echo effect appears when the same me- lodic interval is presented first on ff, then on pp. Ligeti instructs the soloist to play it at different overtones, adding a timbre-re- gister contrast to the dynamic tone. In figu- rative terms, this solo is a continuation of the lyrical line from the Prelude, the third section of the Second and the first section of the concerto’s Third movement. Intermezzo enters as a striking cont- rast: fast tempo, variable meter, distinctly accentuated rhythm and ostinato sound of a tambourine combined with a polyr- hythmic complex. The opening phrase of Intermezzo develops the idea of open strings in bowed instruments. It is echoed by a contrasting phrase in the woodwinds and double bass, which, due to the simul- taneous combination of several scales, cre- ates the feeling of using the technique of groups. The third section – Mixtur – conti- nues the development of the sections In- termezzo, Solo, and is built on a new melo- dic line of a pronounced impulsive nature. The composer creates the note “quasi jazz, parlando” (measure 42). The percussion group is amplified by the bass drum. There is also an expressive timbre development in the form of a comparison of various doublings and mixes. The final section – Kanon – is a vi- vid example of the technique of micropo- lyphony. Starting at the second violins, due to the orchestral crescendo, it grows to tutti (without horns) and then, through the orchestral diminuendo, “calms down” in the parts of the basset horn, bassoon, trom- bone, and strings. This material is very in- dicative from the standpoint of using the technique of micropolyphony, first of all, in terms of tempo – prestissimo, which en- hances the effect of ostinato sound and ir- regularity when repeating its elements. The Fifth Movement is Spectra. Like the Prelude, it represents a single phase of development. The chorale of the ensemble of horns and the soloist is an intonationally updated initial phrase of the soloist in the Prelude. The development is built on tim- bre contrast – a comparison of the sound of horns and other instruments of the or- chestra. The Sixth Movement – Capriccio – includes three sections. The first of them is a bright and dynamic dance. The compo- ser builds it as a timbre-textural complex, combining the melodic line of the soloist (occasionally supported by horns) and the accompaniment of the strings (pizzicato), designated by the composer as “quasi gui- tar”. The second section of this movement, having something in common with the first, is marked by a new melodic figure, which the composer develops polypho- nically and through timbre. The beginning of the third section of this movement is a sharp contrast to the earlier material. Be- ginning with a G-flat-D-flat fifth on the basset horns, it revives the material of the Third Movement of the concerto, and Capriccio “melts” in the soft downward stepping motion of the horns’ fifths, which connect with the trembling layer of fifths, and then their upward movement at the trembling strings. The concerto’s Seventh Movement – Hymnus – is interpreted as a postlude, a gradually fading procession, a chorale. Not being sonorous in technique, it is rep- lete with special sound effects, thanks to the technique of playing frulato on horns, which, combined with a noticeably quiet sonority, creates a mysterious, enigmatic image. The violins play the sul ponticello tremolo, which reinforces this impressi- on. The internal contrast of thematism is exacerbated by a second interval in C-D for viola and cello, with mute and harmo- nics. The material in the double bass part has a different genre nature, the stroke of which (pizzicato vibrato) vaguely resemb- les Aksak from the Third Movement and the dance from the Second. Such an unex- pected artistic turn in the concert finale ret- Harmonia: Journal of Arts Research and Education 23 (2) (2023): 333-345340 rospectively changes the ideological and semantic interpretation of the dramaturgy of the work as a whole and each of its mo- vements separately, introducing elements of elegy and sadness. As for the interaction of composi- tional techniques, in this concerto, Ligeti uses almost the entire range of composing techniques he developed earlier: sonorous layers; intonation, rhythmic, and timbre imitations; and in terms of organizing tex- tured micro-complexes – the technique of cells. All this is united by an original sense of texture (horizontal and vertical). Unlike other concertos, there is no aleatoric in its pure form in the Hamburg concerto, and only some effects arise in the sphere of rhythm and are perceived primarily by ear (Figure 2). Figure 2. The system of techniques of G. Ligeti in the late period of creativity (on the example of the Hamburg concert) It is this synthesis of proven elements and techniques, characteristic of the Ham- burg Concerto, with new timbre-harmonic discoveries (including the use of a natural, non-tempered system) that determines the final role of this work in the composer’s work, reflecting the tendencies inherent in his late style. Scientists from various countries turned to certain aspects and facets of G. Ligeti’s work. Thus, the final role of the Hamburg Concerto allows, according to M. Searby (2010), to reveal in the course of analytical procedures the features of the late style of the Hungarian musician, no- ted, according to most researchers, on the one hand, by the synthesis of trends that determined the evolution of the composer at the previous stages of his creative path, and on the other hand, the incessant search for something new, namely harmonic and microtonal ideas. M. Searby (2010) points out that the composer used natural overto- nes in the horn part of the Trio for violin, horn, and piano (1982) and even earlier in the Third Movement of the Romanian Con- certo (1951), but they represented more of a horizontal line than a vertical one. Research has been carried out on the conception, creation, and performing fate of the Hamburg Concerto. It was ordered to Ligeti, according to Müller, by the Ger- man charitable foundation “Zeit-Stiftung,” established in 1971 by Ebelin und Gerd Buce- rius. The customer expressed the wish that the work requested by him be associated with Hamburg – the place of registration of the foundation – and for the first time performed there. Such a wish, according to the creator himself, gave him the idea to call his concert “Hamburg Concerto” – by analogy with the “Brandenburg Con- certos” by J. S. Bach (Muller, 2003). Desc- ribing the Hamburg Concerto, researchers first of all emphasize the specific nature of its sound due to the choice of instrumen- tal composition: a chamber orchestra with four natural horns, two basset horns, and a large number of percussion instruments. In the comments to the score, the composer indicates that the soloist must also episo- dically imitate the sound of a natural horn and prescribes a special sound production on individual overtones in the indicated places. Explaining his idea, Ligeti empha- sizes that he sought to build a musical nar- rative with the help of a spectrum of tones beyond the traditional temperamental sys- tem, formed into a harmonic layer of his composition (Muller, 2003). Ch. Chapman (2012), a member of the Ensemble Musikfabrik, a contempora- ry classical music ensemble in Cologne, sharing her experience of performing the Hamburg Concerto at the opening of the International Festival of Contemporary Music “Warsaw Autumn” in 2014, descri- bed this work as a compact necklace of se- ven pieces, performed for fifteen minutes and distinguished by beauty, mystery, pe- netration into another world, captivating by the sound of a French horn. Valeriya Zharkova et al., G. Ligeti’s Hamburg Concerto as a Summary of Late Artistic Ten- 341 As the analysis of the Hamburg Con- certo testifies, the “natural” intonation of the horns is combined with the tempe- ramental tuning of the rest of the instru- ments of the orchestra, generating not only special timbre colours, but also marking, according to G. Kurtág (András, 2009), a rapid movement towards a new world of harmony (vertical). The Hamburg Con- certo is perceived as the result of Ligeti’s steady movement while searching for a new sonosphere, in which temperamental sounds coexist with natural sounds and the composer himself called “mistuned mu- sic” (Antonova, 2017). The multipartness of the concerto, based on the contrast of la- conic sections (seven parts), evokes vario- us associations among researchers: A. Mi- nich (2020) reminds of cyclic instrumental compositions of the seventeenth century. E. Schreiber (2019) aims to identify and characterize the key thematic trends in the works of G. Ligeti and demonstra- te their role in shaping and expanding the understanding of the composer and his works. Thus, the attention of the scientist (Schreiber, 2019) focuses on visual spatial metaphors, especially those that resemble fabric, web, labyrinth, and mirror surfaces. Attention is also drawn to the composer’s desire to describe his own creative proces- ses, which largely contributes to his artistic self-identification (Schreiber, 2019). B. Levy (2017) explores the evolution of the author’s style from the perspective of the composition techniques he uses, marking the path from the continuity of the traditions of B. Bartók, through the experimental sphere associated with elec- tronic music to a unique synthesis of the leading trends in academic music of the 20th and early 21st centuries. The cosmopolitan orientation of G. Ligeti’s work is noted by E.-P. Salonen, whose words are quoted in his article by A. Bauer (2012). Therewith, the fact is empha- sized that each of the works of the Hunga- rian composer, who survived the Second World War, is a theatre of the absurd with a pronounced comic tinge, which connects them with large-scale modernist themes and searches (Bauer, 2012; Meleshchenko, 2023). C. Wilson (2004) concludes that com- posers’ ideas about themselves – in articles, program notes, and interviews – had a sig- nificant impact on the music science of the 20th century, shaping not only the percep- tion of particular works but also broader historiographic concepts of the recent past. Specialist (Wilson, 2004) traces one parti- cular way of discourse through the publis- hed statements of G. Ligeti: his “rhetoric of autonomy” seeks to renounce allegiance to “schools” or institutions and downplay stylistic or aesthetic commonality with the work of other composers. It naturally clas- hes with the already familiar pluralistic cultural paradigm of the late 20th century, a paradigm that many postmodern theories, despite its deconstruction of the “unique self” ideology, did not perceive as antago- nistic (Wilson, 2004; Kim, 2017; Nurtazina & Toktushakov, 2017). In a cultural sphere increasingly engulfed by commerce, the image of the radical, autonomous creator, once symbolic of the rejection of the mass market, inevitably finds itself captured by its mechanisms as an obvious advertising tool (Wilson, 2004; Chung, 1987). The purpose of K. Īvāne’s study (2015) was to investigate the microtonal intonation in György Ligeti’s “Hora lungă” for viola solo. It is considered from three perspectives: composing, performing, and audience (Īvāne, 2015). Its special ef- fect, capable of immersing the listener in a strange, magical, nostalgic world, was most clearly manifested in the author’s performance (Īvāne, 2015). The researcher of G. Ligeti’s work – P. Edwards (2015), using the example of the final Passacaglia from his opera “The Great Death”, notes the period of stylistic crisis, which marks the return of the artist to more conventional compositional me- ans. Consonances and tonal allusions in music are indicative of a similar retrospec- tive trend (Yeboah et al., 2022). However, notions of functional hierarchy or centres of pitch do not fully explain the underlying processes that contribute to Passacaglia’s Harmonia: Journal of Arts Research and Education 23 (2) (2023): 333-345342 sense of constant unfolding. The resistan- ce of tonal teleology contains the process of differentiation of pitch material. In this regard, Passacaglia can be considered a further development of Ligeti’s efforts to introduce an individual authorial process into musical material, albeit with an inc- rease in the level of interval transparency (Edwards, 2015). P. Laki (2013) analyses two major works dedicated to G. Ligeti as one of the leading representatives of the European academic composer school of the second half of the 20th – early 21st centuries. Spe- cifically, the specialist (Laki, 2013) offers readers an edited volume of the essay “On Foreign Lands and Strange Sounds.” His training brought together scientists and composers from different countries, many of whom were strongly associated with the composer as co-authors or students. The book provides access to crucial source material and sheds light on many questi- ons about the Hungarian composer’s biog- raphy, analysis of creativity and musical aesthetics (Koniukhov, 2022). The most significant revelation comes at the end of the publication, where the author draws a fascinating parallel between Ligeti and fellow Holocaust survivor I. Kertész, win- ner of the 2002 Nobel Prize in Literature. Beginning in the 1980s, the composer’s entire musical universe received vital new impulses from his meetings with two emi- nent scientists from two vastly different fields. Mathematician H.-O. Peitgen intro- duced the composer to fractals and chaos theory, and the ethnomusicologist S. Arom introduced the incredibly complex rhyth- mic polyphony of Central Africa (Laki, 2013). D. Chua (2008) considers the impor- tance of complex compositional and in- terpretation techniques that arose in the twentieth century on the example of the public and musicological science, in par- ticular, music criticism, the perception of I. Stravinsky’s ballet “The Rite of Spring”. The scientist seeks to reveal the significan- ce of the individual beginning, sometimes expressed in an unprecedented form and manner, causing the public a shock that is opposed to the universal and generally ac- cepted in the world of Music (Chua, 2008). It was in their context that the original, universal, from the standpoint of the synt- hesis of the latest means of expression, the work of G. Ligeti was formed (Chua, 2008). Papagiannakopoulou (2001) writes about the significance of rhythm as one of the leading categories of the musical lan- guage, the compositional technique of wri- ting in the academic art of the 20th and 21st centuries. Specialist (Papagiannakopou- lou, 2001) refers to the works of the out- standing French composer O. Messiaen, stating the fact that rhythm appears in the academic music of the 20th century as one of the most original aspects of the work of the authors of this era, specifically the Hungarian composer (Papagiannakopou- lou, 2001). Research is being carried out on implementing and developing the tradi- tions of G. Ligeti in the musical compo- sition of the 21st century, accompanied by the use of soundscaping (Morandi & Schiavoni, 2022; 2019). The problem of the formation and functioning of digital art is studied, as the implementation of creative searches and discoveries of unknown areas of music, essential for G. Ligeti, as well as the prin- ciples of using computers, diverse types of software to create “new” Music (Schiavoni et al., 2019; Vieira & Schiavoni, 2020). Scientists also investigate the evolu- tion of the intonation fund and the means of recording it and transmitting it to liste- ners, namely through audio applications, when a mobile portable device becomes a musical instrument, and the audience turns into a part of the soundscape (Go- mes et al., 2019; Teixeira et al., 2019). The sphere of the modernized musical space its sociological and ecological nuances are being studied (Vieira et al., 2020a; 2020b). However, showing the musical language of G. Ligeti as a single, voluminous, and complex system requires research, covera- ge, and implementation. Valeriya Zharkova et al., G. Ligeti’s Hamburg Concerto as a Summary of Late Artistic Ten- 343 CONCLUSIONS The publication explored the prob- lem of reflecting the later trends in G. Ligeti’s work in his Hamburg Concerto. The stylistic context and the environment of the intonational fund of academic music of the second half of the 20th – early 21st centuries, within which the individual sty- le of the Hungarian composer was formed, were analysed. As a result of investigating the sub- ject under study, a set of writing techni- ques became apparent, using which Ligeti’s works and, specifically, the Ham- burg Concerto were created. These include sonorism, micropolyphony, group techni- que, aleatoric elements. The study of summarizing the late tendencies of the musician’s work on the example of the Hamburg Concerto helped cover the system of his musical language. It is based on such blocks as thematic mode, dynamic principles, timbre architecture, synthesis of folklore traditions, and mo- dern compositional techniques. In the context of this integral system, the categories and methods of formation and development of musical material by the composer G. Ligeti were identified. These categories and methods appear as micro-thematic elements: expanding, fro- zen, and shrinking clusters; sonorous ver- tical; polyphony (micropolyphonic imitati- on; combination of diverse themes); timbre echo (resonation); transpositions of the thematic source; thematic transformation; variability; genre rhythm; combination of scales; through thematic development; group techniques. During the study on the reflection of the tendencies of G. Ligeti’s late work in the Hamburg Concerto, his main creative principles were determined. Among them, the following are of leading importance: focusing on the genre of the instrumental concerto; modernization of the instrumen- tal concerto; synthesis of academic and folklore traditions; the use of avant-garde style; a combination of modern complex composing techniques and neo-romantic style elements. All of the above determines the sig- nificance and relevance of this paper in va- rious fields, such as musicology, history, methods of performance, and composition basics. This also emphasizes the prospects of the subject under study for researchers in the future since the intonational and stylistic fund of the compositional and technical arsenal are constantly updated and enriched with new discoveries, and, thanks to this, these areas are expanding their boundaries.
