Recording of Hugh le Caine's Dripsody. It is an study for variable speed recorder. It was composed in one night. Le Caine used a recording of a drop of water falling into a bucket, which he re- recorded different speeds, obtaining the heights of a pentatonic scale. Using 25 connectors and the variable speed tape recorder, it produced thousands of sound effects. Dripsody begins with the original sound of the water drop, repetition loop. Shortly afterwards, by adding more loops, the density of the sound increases and an arpeggio figure is produced. The complete work, lasting one minute and twenty-six seconds, was finished at 7.30 am, and Le Caine played it for those who arrived at the laboratory.
