PROGRAM NOTESArkhé is a Greek term that etymologically means the beginning, the origin of all material. The work for solo vibraphone represents this concept through two contrasting themes. The beginning is a mysterious, calm and introspective theme the second theme is turbulent, with lot of dissonances, changing and unstable measures. The main theme appears again with more brio and at the end of the work the final chord of the work leaves the doubt open. Is it minor or major?
