All musical instruments create sound by causing matter to vibrate. The vibrations start sound waves moving through the air.
Most musical instruments use resonance to amplify the sound waves and make the sounds louder.
Resonance occurs when an object vibrates in response to sound waves of a certain frequency.
In a musical instrument such as a drum, the whole instrument and the air inside it may vibrate when the head of the drum is struck.
Most musical instruments have a way of changing the frequency of the sound waves they produce. This changes the pitch of the sounds, or how high or low the sounds seem to a listener.
