Before the piano was invented, musicians would play on an instrument called the harpsichord. The harpsichord was like a piano but had only 60 keys. When Bartolomeo Cristofori grew tired of the harpsichord, he decided to create a new keyboard instrument with a hammer mechanism. When the piano was first invented it only had 49 keys but was followed with a model with 60 keys. Over the years, piano players wanted to make a wider range of sounds, so in the late 1880s, the seven-octave 88-key piano was created by Steinway. The standard for today’s modern full-sized pianos has 88 keys.
