  • Heptatonic Scales

    the possible seven-note arrangements derived from the chromatic scale. In 1929 J. Murray Barbour published an article where he questioned the method used by Busoni, but above all, the results he obtained. Barbour points out that Busoni used a tuning system different from the standard tempered one, because Busoni’s octave has twenty-one different tones instead of the twelve notes of the chromatic scale. Also, Busoni did not recognized enharmonic tones as being equal, therefore a scale containing the notes C D E F G A Bb was counted as different from C D E F G A A#. This happened because Busoni used a harp that contains twenty-one different tones per octave, instead of a piano or any other instrument where the octave is divided in twelve semitones. Barbour observes A serious objection to Busoni’s scheme is that, in accordance with the usual method of notation and with the conception of a seven-tone scale on successive alphabetical degrees, his octave contains twenty-one different tones instead of the twelve that belong to our system of enharmonic temperament on the piano. This would seem to be an unnecessary complication—and restriction—in a proposal that is otherwise so novel. Barbour offers a mathematical procedure to obtain the real number of heptatonic scales that can be derived from the chromatic system, that he calls the “number theory.” His method basically adds all the possible interval permutations between seven tones in the chromatic scale, giving a total number…

  • Romantic Requiem Essay

    sponsorship for the premiere of his requiem. The vocal parts of the romantic requiems had more technical difficulties comparing with earlier settings.
