The Blumeyer comma

08.10.2011 § 3 Comments

I claim the superparticular ratio 2432/2431 as the Blumeyer comma. One eleventh, thirteenth, and seventeenth harmonic each is less than a cent off from an octave displaced nineteenth, and I have developed a JI tuning based on this pun.

Here is the Scala file for this tuning:
