Piano Sinfonia (2018) consists of three sections in simple rounded binary form. Lindenmeyer systems are extensively employed for the transformations of pitch-class sets and the generation of melodic figures in every section. The L-systems are implemented in my own computer program for algorithmic composition written in Java. The Java program generated the piano part and score files for the sound synthesis and processing software RTcmix, written by Brad Garton and his associates. Its instruments of channel vocoder and additive synthesis instruments written by John Gibson and various filter instruments produced all the synthesized sounds.
I am always inclined to keep dynamics and tempo markings as few as possible. I favor the flexibility of interpretation because of my experience with the greatest piano teacher and a friend of mine Niels Østbye. Every Friday afternoon in his studio at Columbia University in New York, to conclude his piano lesson for me, he played one of J.S. Bach's Concertos for Two Harpsichords together with me. It was such tremendous delight for me to explore inexhaustible possibilities of interpretation of those great Concertos with Niels.
