- Why are there twelve different musical notes?
1 Aug 2021
A standard piano has 88 keys: 52 white ones and 36 black ones. On the left hand side are keys that produce deeper tones with lower sound frequencies, on the right are the keys that produce higher tones. In principle there could be more keys on either end, but at some point the frequencies stop sounding musical in our ears, and more keys might become impractical for the performer.
