Gamelan Community Gathering — Contemporary Music for Gamelan is an event dedicated to the exploration of gamelan as an orchestral organism through contemporary composition, uncovering gamelan's culture, forms, and languages. Gamelan is a traditional Indonesian ensemble built primarily from bronze and bamboo instruments, each occupying a distinct layer within a highly integrated musical architecture.
Contemporary Music for Gamelan emerges as a parallel dimension of the already established Gamelan Community Gathering, founded by Sara Andreacchio and Sigrid Winter of the Basel-based ensemble Gamelan Saraswara, and dedicated to traditional Balinese music and dance. A different question posed to the same instruments.
The project originates in a journey. In 2025, through the Global Research Trip of Pro Helvetia, Ivan Liuzzo encountered in Indonesia a highly active and diverse contemporary music scene: the Mi-Reng festival, the work of composers such as Dewa Alit, I Wayan Gde Yudane, Wayan Sudirana, and Arham Aryadi; or ensembles like Nata Swara, Yuganada, Salukat.
This first edition focuses on the theme of reduction. In gamelan, each instrument exists as part of a complete orchestral system: no single element is conceived to stand alone. Moving between solo works and small ensembles, the concert programme challenges this logic: it draws attention to individual voices, isolated timbres, and relationships between instruments rarely heard in such close proximity.
Before the concert, an artist talk with Dieter Mack, Septian Dwi Cahyo, and Krishna Sutedja offers a first point of orientation, opening the space in which the following works unfold.
Contemporary Music for Gamelan forms the evening culmination of a full day dedicated to gamelan at Sommercasino Basel, beginning with the Gamelan Community Gathering from 11:00 to 17:00.
Throughout the evening programme, food will be provided by Indomeal.

Artist Talk
Dieter Mack, Septian Dwi Cahyo & Krishna Sutedja, moderated by Ivan Liuzzo
Concert — 19:00 (approx. 80–100 min, with interval)

Gong
for solo gong (2012) · Arham Aryadi
Maria Luisa Pizzighella
The instrument that orients the entire gamelan orchestra, that marks time and closes phrases, is here on focus. Aryadi works across three resonance points of the instrument, using variations in mallet technique to create timbral colour. Reduction becomes amplification. “Gong is very important in the gamelan tradition. In this work, gong becomes independent. The use of various mallets as a trigger for sound color changes. Besides that there are also three points on the gong that are distinguished so that the sound color develops”.

Selisih Baru
for cello and baritone saxophone (2018) · Dieter Mack
Imke Frank, Sascha Armbruster
Selisih in Indonesian means difference, discourse, conflict in a positive sense; baru means new. Over the course of his career, Mack has spent a total of around ten years in Indonesia, in multiple periods dedicated to the study of Balinese gamelan. Mack builds an imaginary dialogue between cello and baritone saxophone — two instruments of similar register, where similarity is not resolution but the field in which differences become audible. Both musicians sing through their instruments, adding a harmonic layer that belongs to neither tradition alone. "The piece is based on an imaginary dialogue-like 'story', which is not necessary to know, but it determined the formal structure and the different relationships between the two players.

[Es]
for calung, pemade and double bass (2026) · Septian Dwi Cahyo
Tashtego: Pietro E. Barcellona, Ivan Liuzzo, Maria Luisa Pizzighella
A text by Fanon — postcolonial thinker, cited here through Mignolo — is transcribed into Hanacaraka, the Javanese alphabet. That transcription becomes an intervallic system, woven into a Cellular Automata pattern. But the automation is not total: spaces remain where the system stalls, hesitates, breathes. “This work represents a combination between algorithmic compositional tendencies and the basic grammar of the Javanese alphabet, Hanacaraka. [...] The result of this translation is then used to shape the intervallic systems and passages in this work, which are subsequently woven into a Cellular Automata pattern scheme. However, this work is not a total automation — there are various moments of tension between the 'imprisonment' of the system and spaces of freedom”.

Orizzonte – Ascensione I
for 2 jegogan, 2 bassoons, double bass and sinusoidal tones (2026) · Ivan Liuzzo
Commission supported by the Canton of Basel-Stadt
Tashtego: Pietro E. Barcellona, Timm Kornelius, Ivan Liuzzo, Maria Luisa Pizzighella, Gabriella Smart
The piece investigates into the phenomenal perception of sound. The instruments do not emerge: they withdraw. Pianissimo dynamics become a mode of perceptual crisis, the moment at which sound begins to merge with what surrounds it: body sounds, electrical hum, the resonances of the room.

Entropy
For Dual-Tuned Balinese Chamber Gamelan and Contemporary Voices (2026) · Krishna Sutedja
Tashtego: Ivan Liuzzo, Severin Scherrer, Krishna Sutedja, Arthur Wilkens + Wayan Pitriana
The equator — Entropy - is a 100% pure acoustic composition that maps the physical laws of thermodynamic decay onto the microtonal structures of Balinese gamelan and Contemporary Balinese - Orthodox vocal, Bypassing all digital electronics or effects, the piece uses five multi-instrumentalists to stage a physical and acoustic battle between Indonesia's two primary tuning systems: the asymmetric Pelog and the equidistant Slendro. The work is organized into a process-driven, three-phase metric roadmap: Phase 1: The Cosmos (0% Entropy): The ensemble opens as a shimmering, sustained acoustic universe, establishing a baseline texture by introducing heavy string bowing right from the start. The composition is grounded in a rigid 5/2 metric framework running at a steady tempo of 80, driven by the Pelog camp. The Slendro camp running parallel remains tightly controlled, creating a deceptively stable, ordered structural loop. Phase 2: The Collision (50% Entropy): The pristine structure begins to deconstruct. While the original 5/2 metric layer continues to play, a secondary 7/4 metric layer running at a faster tempo of 112 appears and cuts across the texture. This superimposes a 7:5 polyrhythmic ratio, causing the Slendro camp to sound as if it is aggressively rushing ahead while the Pelog camp drags backward. The string bows intensify, and the forced overlapping of these two distinct meters and contrasting tuning systems unleashes heavy, natural acoustic beating in the room air. Simultaneously, the two vocalists step forward for a microtonal glissando duet, sliding their voices into one another to hunt for a shared frequency (tumbuk). Phase 3: The Singularity (100% Entropy): The system undergoes complete rhythmic liquefaction and reaches maximal disorder. The 5/2 (80 BPM) and 7/4 (112 BPM) metric layers continue to play their own independent tempos simultaneously, but are now joined by a final, highly disruptive 11/8 metric layer running at a sluggish, asymmetrical tempo of 58.2 (subdivided unevenly as 3+3+3+2). Running these three independent, prime-number time frames concurrently completely shatters any unified pulse, transforming the music into total acoustic chaos (100% Entropy). This structural breakdown is instantly cut by a single, maximum-velocity acoustic Gong strike, leaving only the raw, natural bronze resonance to fade into absolute silence.

Dialogue (3rd Version)
for kendhang and electronics (1983–84) · Werner Kaegi
Krishna Sutedja
The computer proposes sound events drawn from the linguistic repertoire of the Javanese percussionist; the kendhang recognises and imitates them. Then the metamorphosis begins: the synthesised sounds shift until the instrument can no longer follow. The gap between the two worlds does not close — it becomes the subject of the piece.
"I enter into dialogue with the Javanese musician: I offer him sound events synthesised on the computer, which he recognises and imitates. At a certain point I introduce significant changes. The percussionist remains faithful to his tradition and tries to follow me — until the metamorphosis of my synthesised sounds is so far advanced that he can no longer succeed, due to the limitations of his instrument."

Ivan Liuzzo is an Italian composer and visual designer of Ethiopian and Eritrean origins, based in Basel. His artistic practice moves between musical composition, visual research, the study of Balinese gamelan, and a deep interest in sacred vocal traditions — a personal attraction that leads him to seek direct contact with the places and communities where these traditions are practiced.
His musical work is characterised by instrumental ensembles and constellations conceived to allow for long, apparently static stretches of time, in which perception becomes the primary field of action: the non-recognition of the sound source and acoustic hallucination build a state of tension in the listener. His interest in sacred music is bound to this research: what draws him is the capacity of these traditions to generate a suspended space.
He trained with composer Giorgio Netti from 2017 to 2021, before continuing composition studies with J.C. Walter and Michel Roth at the Hochschule für Musik Basel, where he completed his Bachelor of Arts in 2024. He is currently enrolled in the Master of Arts in Digital Communication Environments at HGK Basel. In 2025 he received the Global Research Project Grant from Pro Helvetia for a residency in Bali, and a Researchbeiträge from the Canton of Basel-Stadt for Tashtego. His work was published in 2025 by ZOK Records (IREI/Tikur) and Dito Publishing (Gentle Fire Basel, in collaboration with Simone Spampinato).
Krishna Sutedja is an Indonesian composer, musician, and gamelan specialist based in Brussels. He received his training at the Indonesian Institute of the Arts (ISI) Denpasar and at Codarts University of the Arts in Rotterdam. He is currently active as composer, performer, and gamelan teacher at the Embassy of Indonesia in Brussels, and is the founder and artistic director of Gamelan Mudrasvara, a Brussels-based ensemble dedicated to the performance and promotion of Indonesian music in Europe. He is also a member of the Polyphème ensemble in Paris, where he engages in experimental projects combining gamelan with darbuka and electronic music.
Werner Kaegi (Uznach, 17 June 1926 – South of France, 16 March 2024) was one of the most significant figures in the history of European electroacoustic and computer music. Born into a musical family in the canton of St. Gallen, he pursued studies in piano, musicology, art history, and mathematical logic in Zurich and Basel, completing his doctoral thesis in 1951 with a mathematical analysis of Bach's contrapuntal techniques. He subsequently studied composition with Paul Hindemith in Zurich, and later in Paris with Arthur Honegger and Louis Aubert, where his encounter with Pierre Schaeffer and Musique Concrète proved decisive.
From 1963 to 1970 he worked at the Centre de Recherches Sonores of Radio Suisse Romande in Geneva. In 1971 he joined the Institute of Sonology in Utrecht, where he developed the VOSIM sound synthesis system and the MIDIM composition programme. Dialogue (3rd Version), for kendhang and electronics (1983–84), places his electronic language in direct conversation with one of the most ancient instruments of the Balinese gamelan tradition. Werner Kaegi passed away in March 2024 at the age of 97.

He is currently undertaking artistic research at the Hochschule für Musik Basel, focused on organ improvisation practices at the end of the Middle Ages.
My experience with gamelan started in 2022 with Gamelan Saraswara in Basel. On the side, the way things often begin before they come to occupy a central place. Then I met Krishna Sutedja, who shared names, ensembles, and experimentations.
In 2025, Pro Helvetia gave me the opportunity to go to Bali. I spent most of a month with Danker Schaareman, ethnomusicologist of Balinese sacred music and the founder of the Basel gamelan group in the 1970s. A month shaped by conversations, journeys into East Bali, and the beginning of explorations that will last a lifetime. In Bali, I also encountered the Mi-Reng festival and a vivid, radical compositional scene: composers such as Dewa Alit, I Wayan Gde Yudane, Wayan Sudirana, Arham Aryadi, and Septian Dwi Cahyo; or ensembles like Nata Swara, Yuganada, Salukat. This encounter reshaped how I think about composition, transmission, and pedagogy.
This event emerges from that journey. Not as documentation, but as a response. I invited several composers I met there, with whom this first edition could take shape, and developed a programme that seeks to bring the current Indonesian gamelan scene to audiences in Basel, while also creating situations of encounter in which Indonesian, Swiss and European musicians can interact through new musical and performative configurations.
