A Piano Study in 17 ET

The genesis of this piece was a piano improvisation which was recorded via midi and used a M-Audio keystation 88 es, pianoteq 3.5, and sonar 8.5.

Once recorded the improvisation was heavily edited –  mostly moving notes (not times) and removing hesitations I judged to be too long. Also the tempo was increased by two. One of the interesting aspects of this piece is that the voice leading is starting to work and I stumbled upon a real progression with resolution that occurs about 1:42. When playing this configuration the main challenge was remembering the relationships of 17 ET mapped to a 12 ET keyboard – for instance a minor 7th becomes a 5th. Many of the chord changes are abrupt since I was moving a pattern of notes in a parallel motion up and down the keyboard as a main generator of the piece. The piece has some decidedly xenharmonic passages. The compositional choices lean towards a balance of consonance and dissonance analogous to 12 ET common practice.

    Dear Chris,

    This is amazing as well. I love this piece. Very fluid and it works very well. Sure there were a couple of abrupt changes as you said, but overall I felt that it connected better as an entity. Love it!
