Syntonic Tuning

Syntonic Tuning is 5-limit just intonation, running left to right by perfect fifths (3/2), and top to bottom by major thirds (5/4):

8/5 6/5 9/5 27/20 81/80
1/1 3/2 9/8 27/16
5/4 15/8 45/32

An intended consequence of this schema is the integration of the syntonic comma (81/80), which pulses when played with the unison (1/1).
