This is the final improvisation for the “Evening Improvisation” series. It is loud, a bit obnoxious, and was totally fun to play. It has some elements similar to the earlier cluster-percussion improvisation, but from a different angle. Specifically, there is a nearly continuous tremolo cluster in the pedals. The feet are usually playing a chord that is accentuated by the hands. I actually found this to be quite technically challenging. And I will be honest, it has got me thinking that I might write a series of etudes for organ!
