The strings of a piano are struck by hammers, which causes them to vibrate. The vibrations of the strings produce sound waves, which travel through the air and can be heard by our ears. The pitch of a sound is determined by the frequency of the sound wave, so the different notes on a piano are produced by strings that vibrate at different frequencies.
The wide range of frequencies that a piano can produce makes it a very versatile instrument. It can be used to play a variety of musical genres, from classical to jazz to pop.
