Relative pitch

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 used by singers to correctly sing a melody, following musical notation, by pitching each note in the melody according to its distance from the previous note. Alternatively, the same skill which allows someone to hear a melody for the first time and name the notes relative to some known reference pitch.
