The history of pianos during the Classical era: The Fortepiano was a relatively small instrument with a small sound, but during the Classical era it became very popular and eventually replaced the Harpsichord and the Clavichord.
What happened musically during the Classical era had a huge impact on the development and the rising popularity of the new instrument; The Pianoforte.
Some important developments were:
W.A. Mozart (1756–1791) loved the new instrument, and wrote an enormous amount of piano music for it. (27 concertos, 18 sonatas and lots and lots of other solo piano pieces.)
first pianos weren’t very large. The forte piano had a keyboard range
of about four octaves at first, but gradually got more. (Modern pianos today have seven octaves plus a third)
