Chromatic Tuner


A chromatic tuner recognizes each of the twelve chromatic (semitone) steps of the equal-tempered scale (C, C#, D, D#, E, F, F#, G, G#, A, A#, B). As such, it can be used to tune any instrument. If you use a chromatic tuner to tune your guitar or bass, however, you'll need to know the pitch (note name) of each string.
