How many white keys are on a piano?

The standard piano has 52 white keys. It also has 36 black keys for a total of 88 keys. The average piano has 220 strings, but that number tends to vary from instrument to instrument.

The first piano, known as a pianoforte, was created in the early 1700s as a take-off on the harpsichord. It was invented by an Italian man named Bartolomeo Cristofor, the instruments keeper for Prince Ferdinand de Medici of Florence. Within 100 years, thanks to improved technology, it had almost completely wiped out the harpsichord in popularity. This is also around the time Ludwig van Beethoven, one of the most famous pianists of all time, began his career.
