Absolute Pitch

Absolute pitch (more commonly known as "perfect pitch") is the rare ability of a person to identify or recreate a musical note without a reference tone. In music a reference tone is the tone that one would hear from a piano or a pitch pipe that can be used to tune an instrument (such a a guitar) or to have a singer(s) starting on the correct note. Basically, these are people who can identify the pitch (the frequency) of a sound, whether it is music (or just noise) on the A through G musical scale from memory. It is estimated that only approximately one in 10,000 people have this ability.
