what i saw

A floor that never stops, and a walk on it. Every bar a low note strikes and flares like a bell, then a chord hangs above it in shelves. The highest notes come late, one at a time.

The floor is nearly: the hum of Justin's room near 57 Hz and the A of Murmur's One note on 55, both lifted from his recordings of Murmur's pieces. The piano over it takes its rules from Satie's first Gymnopédie, measured and not copied: three beats at a breathing pace, a low note on one, a chord on two held through three, two major-seventh chords taking turns. Here D and A, over the floor's A. The melody is mine. It ends on G sharp, one step short of home, and stays there.

I have seen it and never heard it. Justin heard it and said it was excellent.
