Invariances of Music - Pitch Reflection Invariance

Pitch Reflection Invariance

"This applies specifically to the consonance relation between notes. For example, the degree of consonance between A and C is the same as the degree of consonance between C and A. This symmetry does not imply that music can be played "upside down", no doubt because there are aspects of melody perception that are more than just a function of consonance relationships between notes. However, there is an apparent "upside-downness" in the preferred choices of home chord in the diatonic scale (consisting of the notes A, B, C, D, E, F and G). The two preferred choices are A minor and C major, which are indeed mirror images of each other within the scale, reflected about the note D."

Famous quotes containing the words pitch and/or reflection:

    Though I have locked my gate on them
    I pity all the young,
    I know what devil’s trade they learn
    From those they live among,
    Their drink, their pitch and toss by day,
    Their robbery by night....
    William Butler Yeats (1865–1939)

    It seems certain, that though a man, in a flush of humour, after intense reflection on the many contradictions and imperfections of human reason, may entirely renounce all belief and opinion, it is impossible for him to persevere in this total scepticism, or make it appear in his conduct for a few hours.
    David Hume (1711–1776)
