The composition and theory department is a hub for teaching, creativity and experimentation in the field of composition, electro-acoustic composition, composition for the moving image and multimedia creation.

It houses the Centre de musique électroacoustique (CME), a resource centre for the HEM in the field of music technology, sound recording and interactive media. The CME collaborates closely with similar centres such as the IRCAM or McGill University. Moreover, the department is also the skills centre in the field of music theory, whose expertise is centred on Western musical language, but is also expanding to non-European traditions.


The main subjects taught are composition, electro-acoustic composition, mixed and multimedia composition, music writing and music theory.


Teachers of major disciplines

Nicolas Bolens

Head of the Composition and Theory Department - Professor of Counterpoint, 20th-Century Writing, and Practical Writing - Coordinator of General Music Training Modules

En associant traditions et explorations nouvelles des matières sonores, les œuvres de Nicolas Bolens investissent l’espace en valorisant les éléments et les sujets qui se présentent à lui. Combining traditions and new explorations of sound materials, the works of Nicolas Bolens invest in space by enhancing the elements and subjects that present themselves to him. His music is regularly connected to other elements: texts, films, places, evocations... In each context, he seeks an authentic dramaturgy that promotes unprecedented settings. For example, with the Batida ensemble, he imagined "Welcome to the Castle" (2017), three musical acts for musicians moving through the Allymes Castle near Amberieu-en-Bugey. For the Gémeau Quartet, he wrote "La Ville Oblique" (2013), a string quartet conceived as a musical extension of the short film "Un Chien Andalou" by Dalí and Buñuel. Written words, most often poetic, permeate his entire production. He has composed on poems by Celan, Sachs, Mallarmé, Char, Blok, Khayyam, Michaux, Éluard, Basho, Neruda, Rilke, Adonis, Shakespeare... These authors, from various times and origins, have led him to integrate many languages into his works, considering their sonic as well as semantic potentials. Orchestration also holds an important place in his work, rethinking the instrumentation of certain past works. In 2018, he re-orchestrated "Lieder eines fahrenden Gesellen" and the 4th Symphony by Gustav Mahler for the Lemanic Modern Ensemble under the direction of conductor Pierre Bleuse. Commissioned by the association Ouverture Opera, his recent rewriting of Mozart's "The Magic Flute" follows the same approach. Nicolas Bolens has notably collaborated with the Batida ensemble, the Lemanic Modern Ensemble, the Swiss Chamber Soloists, the Ensemble Vocal de Lausanne, the Ensemble Vocal Polhymnia, the Ensemble Vortex, the Basler Madrigalisten, and the Ensemble Vocal Séquence... Born in Geneva, he first studied piano at the Conservatoire de musique de Genève, then completed his training in the composition class of Jean Balissat. He further honed his skills with Rudolph Kelterborn, Klaus Huber, Edison Denisov, and Eric Gaudibert. He is the recipient of numerous composition prizes, including those from the Orchestre de Chambre de Lausanne (1993) and the Banque Cantonale Neuchâteloise (2002), as well as a scholarship from the Leenaards Foundation (1998). An engaged pedagogue and artist, he teaches counterpoint, 20th-century writing, and composition at the Haute école de musique de Genève, where he has been the head of the Composition and Theory Department since 2015. He is also involved in several institutions related to musical creation in Switzerland, including the Swiss Musicians Association, the Archipel Festival Association, the Nicati-de-Luze Foundation, and the Artistic Council of the Geneva Competition.

From October 1991 to June 1993, he was a resident composer with the Orchestre de Lyon. Since 1993, he has been a professor of composition at the University of Vienna. In 1996, he was welcomed as a "composer in residence" at the Lucerne Festival and was honored at the Musica Nova Helsinki festival, which was dedicated to him in March 2000. In 2001, the Salzburg Festival commissioned a piano concerto titled "Abschied" from him. That same year, he was named a Chevalier of the Order of Arts and Letters. In 2004, he was appointed professor of composition at the Haute école de musique de Genève. Learn more about Michael Jarrell.

Luis Naon

Professor of Electroacoustic Composition - Mixed Composition

Born in La Plata, Argentina, in 1961, Luis Naon pursued his musical studies at the Universidad Nacional de La Plata, Universidad Católica Argentina in Buenos Aires, and later at the CNSM de Paris under the guidance of Guy Reibel, Laurent Cuniot, and Daniel Teruggi. He also studied with Sergio Ortega and Horacio Vaggione. Since 1991, he has been a professor of Composition and New Technologies at the Conservatoire National Supérieur de Musique de Paris. Additionally, he taught composition at ESMUC (Barcelona) from 2003 to 2008 and has been a professor of electroacoustics at the HEM de Genève since 2006. From what could be considered his first work, "Final del Juego" for septet and magnetic tape (premiered at Studio 105 of Radio France in 1983), Naon has sought to implement this dual relationship (between America and Europe, between instruments and electronics). He has been awarded the UNESCO International Composers Tribune in 1990 and 1996 (for "Tango del desamparo" and "Speculorum Memoria"), the Fondo Nacional de las Artes (for "Reflets"), the TRINAC Prize from the International Music Council (for "Cinq personnages en quête de hauteur"), the Olympia Composition Prize (for "Ombre de l'ombre"), and the Municipal Prize of the City of Buenos Aires in 1991 and 1995 (for "Speculorum Memoria"). He was nominated for the "3rd Victoires de la Musique Classique" (for Sextuor ". "), "Prix Georges Enesco" from SACEM, and "Luis de Narváez" Prize from Caja de Granada for his String Quartet No. 2. Naon collaborates with various ensembles and institutions such as the Ministry of Culture and Communication, Teatro Colón (Buenos Aires), Musée d’Art Contemporain du Mexique, Orchestre de la Seine-Saint-Denis, Ensemble TM+, Lémanic Modern Ensemble, Interface, Musique Oblique, Musée d’Histoire de Montreuil, Orchestre Philharmonique de Radio France, INA-GRM, IRCAM, Orchestre de Paris, Ensemble Contrechamps, Ensemble Diagonal, Ukho ensemble de Kiev, and in festivals like Musica Strasbourg, MANCA, Festival d'Aix en Provence, Festival Archipel, and Vivier de Montréal. In 1989, Naon composed the music for the parade on the Champs-Elysées and Place de la Concorde commemorating the Bicentennial of the French Revolution. This parade was televised worldwide. The cycle of 25 works "Urbana," initiated in 1991 and completed in 2013, crystallizes under this generic title through "Urbana" (1997). It includes 25 works ranging from acousmatic pieces to symphonic orchestra. He composed the music for the show "Les Princesses" for the opening of the Théâtre-Auditorium de Poitiers in partnership with choreographer Odile Azagury. Nearly 3 hours of music ranging from solo electroacoustic (for choreographers Anna Ventura, Karine Saporta, or Dominique Boivin) to pieces for 15 instruments and electronics (for choreographers Carolyn Carlson, Héla Fatoumi, Blanca Li, etc.). This entire production is captured on a double CD under the Empreinte Digitale label. Recent works include "Quebrada/Horizonte" for orchestra, "Pájaro al borde de la noche" for cello, electronics, and ensemble premiered at the recent Présences festivals of Radio France, "Ébano y Metal" for the Lemanic Modern Ensemble (Switzerland/France). Other notable recent works include "Rastros" for the ensembles Stick & Bow and Paramirabo of Montreal (featured in a monographic concert and video recording) and his "String Quartet III" (premiered at the Evora Festival in 2021, then at Archipel 2022 and projection space of IRCAM in 2023). His latest piece, "Fueye," concertino for bandoneon and ensemble, was premiered by Juanjo Mosalini and the TM+ ensemble at the Maison de la Musique de Nanterre in October 2022, followed by performances at La Seine Musicale and Gennevilliers in May 2023. Naon's works are published by Henry Lemoine, Gérard Billaudot, and Babelscores. Learn more about Luis Naon.

Gilbert Nouno

Head of the Centre de Musique Électroacoustique - Professor of Electronic Music - Multimedia Composition - Interactive Video Design - Internet Music - Interfaces, Digital Instrument Making & Immersive Systems - Concept & Creation, Open Space

Composer, sound artist, pedagogue, and researcher, Gilbert Nouno creates music that is highly in tune with visual arts and digital technologies.

As a visual artist under the name Til Berg, he combines the synesthesia of sound arts with other media. Using music and sounds, he generates abstract and minimalist visuals with traditional and digital media such as video and lithography. Gilbert Nouno's collaborations are marked by aesthetic plurality with many artists such as Pierre Boulez and the Berlin Philharmonic Orchestra, George Benjamin and the London Sinfonietta, Jonathan Harvey and the Arditti Quartet, saxophonist Steve Coleman, and flutist Magic Malik... A laureate of the Villa Kujoyama in Kyoto in 2007, and the Villa Medici, Académie de France in Rome in 2011-2012, Gilbert Nouno joined the Centre de musique électroacoustique (CME) of the Haute école de musique de Genève as its head, teaches composition at the Royal College of Music in London, and is a visiting professor invited by the DAAD in Detmold (Germany).
