If each note in that song was replaced by a piano’s hammer massaging a chord and slowed down 1000%, you could hear the hammer bouncing from the string several times. The key may only be pressed one time for each note, however, (like Rhianna) it is struck several times. Something you would never notice at full speed.
It would be beautiful.
I was wrong, I was thinking of it in a different way, if it was 1000% it would go in reverse. The song is ten times slower, but that’s because it’s 1/10 it’s normal speed, so it would be 10% slower…technically.
But wait, if a song is 100 measures, and normally 1 measure lasts 15 seconds, then the rate is 1meas/15sec. This can as well be expressed as its inverse, 15sec/1meas. Therefore, multiply by 1000 and get 15000sec/1meas. We then have a song 1500000sec long. 1500000sec * 1min/60sec = 25,000 min….
