Impefaltrep means implementation, efficiency, alternation, and repetition (aspects of a composition). This is a 3min and 40sec piece. It is to be played with 2 separate pianos. I worked a very long time on this piece, and I am especially proud of how the end and the beginning turned out. Enjoy this piece, and dare try to play it in real life! (edited recently in 2019 to make it actually playable).
