This is a complete performance of Schuman’s Three-Score Set, with each set played straight, and followed by several variations. The variations transform the themes in a variety of ways. The tuning is all scales derived from otonal scales in the tonality diamond to the 31-limit. The specific scales change frequently. In the scores shown below, you can see in the middle the otonal scale for each measure segment.
