Synthetic Sonata is a very difficult piano solo that employs pointillism. A synthetic scale is used: C, D, E, F#, G#, A#. The piece is in true sonata form with a theme, development, and a recap. What"s interesting is that there is only one transposition of the scale. This allows for all 12 notes to be used in the development section. Kraftig is German for "strength." This is a duet for 2 pianos which is fun to play and appeals to general public audiences.
