Many musical instruments transfer mechanical energy into sound energy. When a string is plucked, it vibrates, causing the surrounding air to vibrate as well. This vibration of the air creates sound waves that we perceive as music. The pitch of the sound depends on the frequency of the vibration, while the loudness depends on the amplitude of the vibration.
Here are some examples of musical instruments that transfer mechanical energy into sound energy:
* String instruments such as the violin, guitar, and piano
* Wind instruments such as the flute, clarinet, and trumpet
* Percussion instruments such as the drum, cymbal, and xylophone
