The fourth Evening Improvisation attempts to use the organ as a percussion instrument. This sort of thing has been done before, but one distinct advantage to this improvisation is the organ itself. All organs may have similar aspects while still being unique to their space and builder. To be totally honest, the instrument at the Monastery is not great. It’s a mediocre 1980 Moller with some nice colors and everything chiffs. No kidding, even the celeste chiffs. Then why not use it for something! The chiffing combined with the slow speak of the lowest register pipes creates something that I think sounds like a musical saw, only much richer (and less silly?).
A small note about the improv: the clicking you hear is my wedding ring hitting the keys. I was really digging in!
