Description: This Passacaglia 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 accompaniment. The melody of the leading voice progressively expands. The melody of the accompaniment uses the palindromic nature of the scale and changes in the middle section.
