Questions 1-3 are about the following passage.

The piano is one of the most popular instruments in the world. The modern piano was invented by Bartolomeo Cristofori. Cristofori worked as the keeper of instruments for Ferdinando de'Medici, the 'Prince of Tuscany. It is unclear when he created the first piano, but the oldest Cristofori pianos that exist today are from. the 1720s.

Cristofori knew a lot about the clavichord and the harpsichord before he made the piano. The clavichord and the harpsichord were good instruments but were flawed. The clavichord was not loud enough to be used with an orchestra, while the harpsichord could not play very expressive notes. Cristofori invented the piano to have an instrument that was both loud and expressive. Cristofori's piano became famous because of a respected writer named Scipione  Maffei. Maffei wrote an article about the piano with a diagram. of it. Most people that would become piano builders found out about the piano from this article.

Interestingly, Johann Sebastian Bach did not like the piano when he first heard it. He thought the high notes were not loud enough. Eventually, he came to like it. Wolfgang Mozart was one of the first musicians to use the piano. He composed much of his music on it. Still, the pianos in Mozart's time were different than they are now. Today, the piano is one of the most well-known instruments in the world. It is used in orchestras, musicals, and in many other popular forms of music.
