Document Summary
When pitches are perceived in the context of musical melody our perception of pitch becomes more di cult. E. x giving notes names in western music refer to pitch chroma (c, d, e) Chroma"s are identical when separated by an octave and are part of a whole dimension from pitch height. Octave equivalence: tones separated by an octave inhabit the same chroma category. Within an octave changes in chroma are also changes in pitch height (the dimensions are therefore somewhat di erent but no independent) Auditory cortex in the brain maintains distinct representations for pitch chroma, pitch height are reported in fmri study. Melody being played in a di erent key (c to d major) Even when the notes are moved, the relationship (intervals) between the pitches are same and people use this to recognize a melody causing them to think both the melodies are the same.
