Tremolo

Piece for one performer, two controllable spinning aluminium plates inside an aluminium tube, organ pipes, and a wind machine.

Alongside the premiere of Le Slie’s at Klang Moor Schopfe 2025, I had the opportunity to create a commissioned composition. For this piece, I built another instrument with the aim of deepening the Doppler effect that my instrument Le Slie’s had been working with.

It turned out, however, that I was not producing pitch modulation, but amplitude modulation. This shifted the resulting acoustic phenomenon towards what is known as a tremolo effect. I therefore had to rename the piece, since I had first called it Doppler even though there was no Doppler effect at work. It is now called Tremolo.
