New Music by Karlheinz Essl

Gerhard Eckel: electro-dynamic feedback system Karlheinz Essl: modular electronics Recorded live at Studio kHz on May 1, 2026. Mastered by Gerhard Eckel. https://www.essl.at/div/rhibozom.html YouTube video: https://youtu.be/JKOG74rIdNs rhibozom is a duo of Karlheinz Essl and Gerhard Eckel working at the intersection of electrodynamic feedback, analog synthesis, and shared physical instrument-making. Gerhard Eckel performs on an electrodynamic instrument played with ferromagnetic objects that act as resonators, modulators, and sound sources within the instrument's pickup and speaker field. Karlheinz Essl performs on a compact modular synthesizer, its sounds projected through a separate loudspeaker on the shared table. Both performers place, move, dampen, and excite the resonating objects — the handling of physical material is a joint practice, not divided by instrument.

My first experiment with the Music Thing Modular Workshop System, a powerful compact modular desktop system. In this patch, I was creating a chaotic system using two ring-modulated oscillators with frequency modulation from two slope generators and a self-resonating bandpass filter. Part of the work-in-progress "My Daily Wobble" (2025 ff.) https://www.essl.at/works/my-daily-wobble.html Performed live at Studio Ölberg (25 Jan 2026)

Free improvisation on a MakeNoise 0-COAST in two parts, using the two generators of a KORG NTS-2 oscilloscope as modulation sources.

Nava Hemyari (voice) & Karlheinz Essl (electronics). Part of the album "Karanava" (2025). Two composers, differing in terms of gender, age, cultural background and instrument, leave their writing desks and venture into the unknown. Despite — or perhaps because of — these differences, they create something genuinely new together: songs composed instantly, without any prior planning, in the moment. https://www.essl.at/div/karanava.html

A composition for melodica and live-electronics by Karlheinz Essl. It was commissioned by the Non-Piano/Toy Piano Weekend and premiered by Steven Tanoto on November 22, 2025 at Resonanzraum St. Pauli in Hamburg. Recorded and produced by Karlheinz Essl. If we think of the organ as a giant mountain, then we can think of the melodica as a kind of shrunken-down version of that - a tump. In my piece, this weak and humble instrument is given a powerful voice so that it can match with her great ancestor, the organ. The play on a melodica is manipulated by a sophisticated computer program (written in Max) that expands the sound in many dimensions. It is controlled by the player while performing the meticulously notated score. However, the musical result is not just an "orgified" version of the melodica. It is full of microtonal deviations, harmonic shifts and glissandi that are difficult to achieve on an organ. In a mesmerising interaction between the melodica, the performer and the computer software, we can listen to the mysteries of the reeds... In a certain sense, the piece can be heard as a parable, telling the story of weakness and strength through the language of sound.

Binaural production - listen with headphones for full immersion! I embarked on a dreamlike journey through Cologne when I visited the Museum Ludwig that presented collaborative works by John Cage, Merce Cunningham, Jasper Johns, Cy Twombly and Robert Rauschenberg. An interactive installation by the latter encouraged visitors to engage in unusual activities such as clapping, shouting, singing and whistling. Occasionally, you would also hear the gentle voice of John Cage. Afterwards, I immersed myself in the cathedral, which resonated with the sounds of its visitors.

I spent the last weeks in Apulia, a beautiful landscape in Southern Italy, charged with history and stories. The symbol of this region is the Pumo - a traditional ceramic figurine which depicts a stylized flower bud. This gave the title of a new piece for my H.E.A.D. cycle: a immersive sound portrait of this landscape. When listening, you will visit a street market in Ostuni, witness a procession with a marching band in Cisternino, hearing the organ of the Basilica of Lecce and some school girls in the historic center of Grottaglie.

Im Gespräch mit der trans-Art Künstlerin Astrid Rieder spricht Karlheinz Essl über die Zeit, „Zufall und Notwendigkeit“ (Jacques Monod), über die Dialektik von Gemütlichkeit und Unbequemlichkeit in der kollektiven Performance und die Improvisation als Rettung. Nach langjähriger Erfahrung mit digitalen Werkzeugen experimentiert Karlheinz Essl seit einiger Zeit mit einem hochempfindlichen analogen modularen Synthesizer namens 0-COAST, den er in Interaktion mit der Zeichnerin und trans-Art Performerin Astrid Rieder allein aus den Schwingungen des Geräts zum Klingen bringt. Hier die Transkription dieses Interviews: https://essl.at/bibliogr/essl-rieder_3.html

Generative sound environment for an art installation by Beat Zoder, written in MaxMSP. 6-channel live performance with Max9 at Studio kHz on 12 Dec 2024. Binaural rendering with REAPER and dearVR. Listen with headphones! https://essl.at/works/hirsch-roehren.html In 2006, Swiss artist Beat Zoderer and Austrian composer Karlheinz Essl were commissioned to create a collaborative work for the music festival Stanser Musiktage. In an abandoned repository situated in the heart of the Swiss alps, both artists were setting up a room installation made of sewer pipes. Those plastic parts of different lengths were equipped with funnel speakers driven by a customized computer program written in MaxMSP by Karlheinz Essl. Utilizing realtime composition algorithms which the composers develops since 1985, his software created an ever-changing sonic environment which never repeated itself. Seen from outside, the structure resembled a giant jackstraw heap which invited the public to explore the space. Sounds that were projected from the loudspeakers through the pipes commuted through the air, creating a mysterious atmosphere as if some hidden creatures were talking to each other in an incomprehensible, yet compelling language.

First encounter between the organist Jeremy Joseph and the composer Karlheinz Essl on his 0-COAST modular synth on 2 December 2024. We met in St. Ursula, a beautiful baroque church in Vienna which houses three fine organs, one of which - a sublime 7-rank Italian instrument from the 18th century - is used on this track. There were no preconceived musical ideas or any kind of preparatory sketches for the improvisation. It is simply an atmospheric late-night ‘jam session’ recorded in the darkness of the sanctuary. It captures us getting to know each other, finding one another and it illustrates the process of musical consolidation through improvisation. https://essl.at/div/becoming-one.html

Soundtrack for a stop-motion movie by Hervé Bacquet, performed on a 0-COAST modular synthesizer. Produced at Studio kHz 2024. Watch the film: https://youtu.be/1kp6zm9oWSY

The Maelstrom is a gigantic vortex in the North Sea, described by Edgar Allan Poe in his short story "A Descent into the Maelstrom" (published in 1841). Its power is so great that it can suck in even large ships and crush them to pulp. For my piece, I constructed a kind of Maelstrom mechanism with Granular Synthesis, written in MaxMSP. It pulverizes sounds and recombines them into new sonic structures that can be controlled during a live performance. The underlying sound material comes from an improvisation on my MakeNoise 0-COAST modular synth, which is also used as a sound device in this piece. https://essl.at/works/maelstrom.html The premiere took place on March 22, 2024 during my portrait concert at Bilkent University in Ankara, Turkey, performed by myself.

Radiofeature von Jörg Duit über das Improvisationsduo OUT OF THE BLUE mit Agnes Heginger (Stimme) und Karlheinz Essl (Live-Elektronik). Erstsendung am 20.3.2018 im Zeit-Ton auf Ö1. https://www.essl.at/bibliogr/duit-sommerwellen.html Die charismatische Sängerin Agnes Heginger und der kongeniale Komponist und Elektroniker Karlheinz Essl nehmen Gedichte als Ausgangspunkt für ihre Performances, die von beiden aus dem Moment heraus vertont werden. Das Offene und Unerwartete steht im Zentrum dieses Prozesses. Dabei reagieren sie auf den entstehenden Raum/Klang, die Zuhörerschaft, die gesprochenen und gesungenen Worte, die Soundscapes und Geräusche, die hörbaren oder nur gedachten Gedanken. Hinter diesem sich fortwährend transformierenden Gespinnst wird etwas Neues sichtbar. Erleben Sie ein fesselndes Experiment, in dem liebevoll ausgewählte Text- und Klangfragmente zu Spielbällen werden, mit denen Agnes Heginger und Karlheinz Essl virtuos jonglieren.
