Passacaglia for Piano

"Passacaglia for Piano" by Hugues Bedouelle is entirely written in scale (0,2,4,6,7,9,10), which corresponds to the ascending melodic minor scale of G. The score comprises two voices whose roles alternate between leading voice and accompaniement. The melody of the leading voice progressively expands. The melody of the accompaniement uses the palindromic nature of the scale and changes in the middle section. The score was interpreted with the K2 Grand Piano of Pianoteq in Studio Recording BA mode.
