Relative pitch is the ability of a person to identify or re-create a given musical note by comparing it to a reference note and identifying the interval between those two notes.
Relative pitch implies some or all of the following abilities:
- Determine the distance of a musical note from a set point of reference, e.g. "three octaves above middle C"
Identify the intervals between given tones, regardless of their relation to concert pitch (A = 440 Hz)
the skill is used by musicians to correctly sing / play a melody or chords and interpret musical notation. Alternatively, the same skill allows someone to hear a melody for the first time and name the notes relative to some known reference pitch.
