Original Wikitext content:
**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 //[[http://launch.groups.yahoo.com/group/tuning/message/100427|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.
