Urmas Sisask

Estonian TV Girls' Choir with Urmas Sisask at St Paul's cathedral in London, 2008. Urmas Sisask (9 September 1960 – 17 December 2022) was an Estonian composer.

Biography Sisask was born in Rapla on 9 September 1960. One of the major inspirations for his music was astronomy. Based on the trajectories of the planets in the Solar System, he created the "planetal scale", a mode consisting of the pitches C#, D, F#, G#, and A. Later, he discovered to his surprise that this was exactly the same as the Japanese Kumajoshi mode, which is also known as the Japanese pentatonic scale.
