Musical cells

Musical cells is a system of Mario Pizarro for constructing circulating temperaments. Recently he has connected this to a system of stretched octaves he calls "toctaves". This is discussed on The corrected progression of musical cells.

Toctave

Toctave (short for "True Octave") is a frequency ratio of 27 * 2^(1/4) / 16 (ca. 1205.865 cents) which Pizarro came up with in connection with his theory of musical cells.

[math]Toctave=\frac{27}{16}\sqrt[4]{2} \approx 2.0067870065670918\dots[/math]

This is 1/4 of a Pythagorean comma sharp.
