Sound is produced by bodies that vibrate or shake, for example, if a vibrating tuning fork is placed over a column of air, the fork sets the air into vibration, and sound is transmitted through matter such as air or water.

The matter through which sound is transmitted is called a Medium. Sound is transmitted through a medium in the form of vibrations or waves.

A tuning fork is a small steel instrument, which is used to tune instruments, by striking it against something to produce a note of fixed musical pitch. The sound they make is totally pure.

The pitch of a sound depends on the frequency while the loudness of a sound depends on the amplitude of sound waves.
