The first true piano was invented by one man—Bartolomeo Cristofori (1655–1731) of Padua. Three pianos by Cristofori survive, however, their sound differs considerably from the modern piano. Its range is considerably narrower—54 rather than 88 keys.

In the late 1880s, popular piano manufacturer Steinway created the 88-key piano that is the standard today. The thing is that such a piano features a full seven octaves and a few more notes.


Why did he stop at the exact number of 88 keys? Actually, it wouldn't be easy for our ears to hear notes beyond the ones present on this piano. Composers just don't use such notes in their music!

There are 52 white keys and 36 black keys on the modern piano.
