Ombre 1 is part of a cycle of solo pieces with and without live electronic devices (Ombre 2 for clarinet and electronics, Eleistä for 6 cellos and electronics, Nodus 1 for clarinet, Nodus 2 for cello). These works were written for musician friends who are very committed to contemporary music. Ombre 1 was written for Anssi Karttunen. In the two works, Ombre 1 and Ombre 2, the electronic part is a shadow of the instrumental part and is integrally constructed with sounds of the solo instrument. The sound atmosphere is the one of composition, not a technological demonstration (as in works such as Jeux for piano and live electronics). D. Cohen
