M=h(n) (Harp Solo)

A harp has 7 pedals, which correspond to 7 notes, i.e. do-re-mi-fa-sol-la-si. Each pedal can take three different positions, namely flat, natural and sharp. Therefore, a harp can be set for 2,187 different modes (scales) (3 to the power of 7). The instrument could be considered as a "function". The 7 notes can be mapped to 2,187 different scales. The name of the composition "M=h(n)" is derived from the mechanism. In this composition, the 22 different scales are used . This piece has been premiered by Makiko Suzuki in "La Folia-a concert for openly-invited compositions" on July 21, 2017, in Tokyo, Japan. The composer thanks to her for her invaluable advice on the music
