compositions

František Hruška's compositional work moves on the border between electroacoustic music, sound art and experimental composition. Through field recordings, obscure sound objects and his own electronic instruments, he creates layered sound situations focused on detail, space and conscious listening. He studied musical composition, for example, at the Royal Conservatory in The Hague or at several intensive residencies at the Institute of New Music Ostrava Days of New Music.

Below is a list of published compositions, fixed-media, sheet music, graphic scores, soundtracks, etc., including recordings

ODIO (2026) (work in progress)

A three-part spatial composition created for the specific music application ODIO for iPhone.

Common is the Ground (2026)

Searching for common ground. Performative musical reflection – action, and interactive sound installation – interaction. In electronic and human systems, meaning only arises when we agree on where the zero is. The ground. Without a reference point, the signal is noisy, a poorly grounded system creates loops, and isolated elements are inaudible. Visitors close the circuit by touching: bodies conduct current, resistance turns into sound. People are not perfect conductors – but the system does not play without them. A common language only arises when the elements are connected.

Created for the Academia Film Olomouc festival

Footage coming soon

INKBLOOD (2024-2026) (work in progress)

Inkblood is a video game from Hey Bird! studio and published by Critical Reflex. I created an original musical soundtrack for Inkblood together with Jonáš Svoboda. The music is quite complex, using a very wide range of approaches, instruments, techniques and techniques... So you better listen to it. (When it comes out)

The expected release is in 2026.​

Grandma's pickles (2026)

Inbetween composition and improvisation. I invite the audience to look under the hood of my compositional process during a live performance. The situation was both improvised and composed, as I find that in my practice these approaches intertwine to an indistinguishable extent.

Neboj, neboj (2026)

Scenic music for the production of Neboj, neboj based on the book about fear by Milada Rezková, directed by Štěpán Gajdoš, and performed by Studio 60+.

Created in collaboration with guitarist and composer Jakub Šimanský , the stage music combines acoustic guitar, banjo and lap steel guitars, exciting synths and sequencers, and ambient synth surfaces.

Štěstí, zdraví, pokoj svatý (2025)

A six-channel spatial music installation for a permanent nativity scene exhibition in the Museum and Gallery in Prostějov.

This musical composition is a gentle, almost meditative piece, supporting the atmosphere of Christmas gathering in contrast to the hustle and bustle. At the same time, however, it carries elements of tension associated with the complicated story of the birth of Christ, in contrast to the typical nativity and carol revelry and naivity. I used almost exclusively acoustic instruments and field recordings of the sounds of nature, because the architecture of the entire exhibition is built by hand and from natural materials, reminiscent of a stable, the place of Christ's birth. It was created in cooperation with the association Omlouvámesepardón.

Review

That is a conflict (2025)

When we part from superficial proximity, we inevitabely invite conflicts to arise. We are cliffs separated by a ravine. Opening up means closing the distance between. When cliffs move closer, certain convexities may crush with the other. That is a conflict. Let us not be afraid of it.

Composed and performed during residency at the Ostrava Days of New Music Institute.​

And Then  Crickets... (2023)

Intimate sounds for an intimate ensemble in an intimate yet open space. Year before I've composed and played a “concert for birds”, this time it's a concert for crickets, or rather a concert with crickets. The soft sounds composed for an oud, flute, and bongos, are timed to interact with the crickets in different stages of their daily sonic activity. A large part of uncertainty and indeterminacy is to be expected. The weather conditions among many other things can drastically change the outcome. Thus, the performers are not following a strict score, nor is it purely improvised. There is a certain part precomposed and different rules and conditions which allow or force the performers to take a decision and carry out a certain action. In this sense, the composition is highly site & time-specific, however simultaneously, it could be done wherever and whenever where there are crickets active. And then — crickets…

Lofofora Quarry (2023)

For two days and one night I've been commissioned by Obscura Radio to collect field recordings from the flooded quarry in Kurovice, Czechia, to then make a composition on the spot and discuss the process.

Here's the result

Connect the Dots (2023)

The municipality building in Den Haag (...) The absolute whiteness and sterility of the interior, the vast openness, the vertical spaciousness, the large number of entrances and exits, the layers of railings, stairs, and floors… And its sonic nature is equally as blank. Often the only sounds present are human voices, spoken words. (...)

People, voices, and emptied-out concepts and words, politicized and problematic terms and phrases, the most common and overused words of contemporary discourses, which have been repeated over and over until the inevitable thorough depletion of meaning. And I use the audience as people who carry these voices, which are not theirs. (...)

Listen to the Iterative Process of Peter's Philosophy (2023)

A collection of works by students, alumni and teachers from Sonology in dedication to our beloved teacher and colleague Peter Pabon. A small gift in return for his perpetual altruism and charming nature.
All composers were asked to make a piece that included a notion of human voice. 

My piece is track nr. 1 composed solely from Peter's speeches.

WHAT ARE YOU DOING I SAID TAKE IT EASY BUT SERIOUS CRUNCHY SQUARE SILENCE!!! (2023)

The conductor is an annoying prick, asking the impossible from the poor performer, while the composer is sitting in a chair having fun and laughing at them both.

It's a race. Three laps of fixed media quadrophonic track. Four directional microphones in four corners of the performers cage corresponding to the four speakers of the quadrophonic setup. Conductor is giving instructions on what sound should be played at what mic at what time based on a video score. Hundred different objects on the table. The performer has to react immediately. The poor performer didn't know beforehand what instruments and what score he will be playing. He was kept in the dark.

At the end they both win and deserve a medal, because we are all losers.

Food for Thought (2022)

Soundwalk in collaboration with Yannis Mihos

 

The key difference between unity and uniformity is their acceptance of differences; when there is unity, people tend to tolerate and accept differences, but uniformity implies that everyone is alike, so there is no room for differences. In the same way everyone thinks they know what pizza is, while in fact, that’s not as simple.  (...) This continuous site-specific audio walk piece guides the listeners through the streets of the Hague in the Netherlands, moving them from one pizza place to another, wearing headphones connected to their mobile phones.

Kosmic Meadows (2022)

Concert for birds – A tribute to Kozmic meadows and all living beings

As a part of Radio Art Zone's project in cooperation with Magdalena Maderlova & Michal Kindernay.

"Kozmic meadows are a system of floodplain meadows situated in the Opava region, northeast of the Czech Republic. This area was formerly intended for gravel mining and experienced difficult times of water drainage, aggressive terrain destructions, and extraction of resources. These activities disrupted the natural balance and caused the loss of biodiversity. Kozmic meadows are now, thanks to the long-term commitment and dedicated work and care of the local community and the company Semix, full of life and accommodating hundreds of species of birds and plants, amphibians, Exmoor ponies, and an ornithological observation station.
(...)
As a tribute to Kozmic meadows and all living beings, we commissioned Martin Režný and František Hruška, two local experimental musicians, to perform a Concert for Birds. The improvised performance took place near the bird reserve in the dusk of August 16th, 2022."  from: radioart.zone/thursday-22-september

So many books, when will I read it (2021)

Visual score for voices, accordion, bendir, bongos and synthesizers

 

I spent hours and hours looking at these bookcases by Jana Beranová (1932), originally a Czech poet and translator who has lived in Rotterdam for a long time. And that is just one of many, her entire two-story apartment is under siege by books that get tangled under your feet and between the bowls in the kitchen. In addition to all that beauty, there is also a bit of distress, a constant reminder that it is not possible to read as much as one would like. It reminds one of the limitedness of time. It must have helped Jana live to her healthy 90 years.

So if you can't read the books, at least try to play them.

 

Dedicated to Jana

A Day in the Life of My Laptop (2019)

Fixed media

 

What does my computer hear?

Computers not only calculate and provide results, but they also have their own sensory organs that allow them to receive information from outside and inside. And these "hearing organs" often also distort sound in many ways, contributing their own character and resulting in an interpretation of sound from the subjective listening angle of that particular computer.

In this composition, I look into what my computer "hears" at times when I don't expect it to be "listening."

By recording all the sounds the computer perceived, both internal and external, over a longer period of time and then composing them into two minutes, I created something like a time-lapse - A Day in the Life of My Computer.

Simply Pulses (2019)

Composition created in an analog studio at the Institute of Sonology at the Royal Conservatory of The Hague.
Inspired by the composition principle of Terminus I by Gottfried Michael Koenig.

CTG (Czech Train Generator) (2019)

When I was studying in Holland, far from home, and feeling sad about Czech sounds, I created this system that allows a performer to synthetically create sounds similar to Czech trains, because trains in the Netherlands are sterilely quiet.

 

CTG is a digital musical instrument for live performance that I programmed in SuperCollider. This is a short recording of a composition/performance on this instrument. All sounds are purely digitally synthesized and digitally processed.

Passing by (Retro vision) (2019)

Acousmatic fixed media composition, created in the analog studio BEA5 at the Institute of Sonology in The Hague. The source of the composition is purely analog sounds (pulses, sine waves, noise) and all sound processes are also done only with the help of analog technology. The composition was originally created for five channels, then mixed into stereo.
