Email patrick@bic.mni.mcgill.ca Abstract Absolute pitch has proved useful as an alternative perspective from which to investigate various cognitive faculties. A new functional magnetic resonance imaging study published recently in BMC Neuroscience adds new data to the ongoing debate concerning the neural underpinnings of this unusual ability. Root fifth sixth flatted seventh octave ninth flatted seventh octave ninth octave. When played with the right rhythm and attitude these musical intervals will be recognized by many people as the main thematic refrain from So What by Miles Davis. We are able to discern this because the pattern of intervallic relationships of both pitch and time forms the melody no matter the starting pitch. If given the information that the root note is D any trained musician will be able to compute the rest of the note names by identifying the intervallic distances between each note of the melody and the root or any other note that has been determined yielding D A B C D E C D E D. This ability is referred to as relative pitch. A small minority of musicians however can identify all the notes absolutely each in isolation and without reference to any other note. In other words they possess some sort of internal template a stable representation of pitches to which they can compare the incoming signal and subsequently identify the notes by name by sounding them on an instrument or other responses. This is referred to as perfect or absolute pitch AP . A comprehensive review of the factors influencing the likelihood of acquiring AP is far beyond the scope of this brief commentary although the two most frequently .
