Septimal Minor Third - in Equal Temperament and Non-Western Scales

In Equal Temperament and Non-Western Scales

Twelve-tone equal temperament (12-TET), as commonly used in Western music, does not provide a good approximation for this interval, and quarter tones (24-TET) do not match it well either. 19-TET, 22-TET, 31-TET, 41-TET, 53-TET, and 72-TET each offer successively better matches (measured in cents difference) to this interval.

Several non-Western and just intonation tunings, such as the 43-tone scale developed by Harry Partch, do feature the (exact) septimal minor third.

Famous quotes containing the words equal, temperament and/or scales:

    Doubts of all things earthly, and intuitions of some things heavenly; this combination makes neither believer nor infidel, but makes a man who regards them both with equal eye.
    Herman Melville (1819–1891)

    That a good fit between parental handling and child temperament is vital to help children adapt to the imperatives of their society is a crucial concept that can be applied to other cultures.
    Stella Chess (20th century)

    It cannot but affect our philosophy favorably to be reminded of these shoals of migratory fishes, of salmon, shad, alewives, marsh-bankers, and others, which penetrate up the innumerable rivers of our coast in the spring, even to the interior lakes, their scales gleaming in the sun; and again, of the fry which in still greater numbers wend their way downward to the sea.
    Henry David Thoreau (1817–1862)
