The higher the frequency the higher the pitch or tone of the sound.

The word that musicians use for frequency is pitch. The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low. Instead of measuring frequencies, musicians name the pitches that they use most often.

Explanation:  The frequency of a sound wave is the number of vibrations that occur per second. The pitch of a sound is a description of how high or low the sound seems to a person. The pitch a person hears depends on the frequency of the sound wave.
