Frequency is usually referred to as the pitch of a sound. A high pitch sound reacts to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. Mostly, people who can sing are capable of detecting a difference in frequency between two separate sounds that is as little as 2 Hz.
