The γ (gamma) scale is a non-octave repeating musical scale which splits the neutral third (just: 347.41 cents , ET: 350 cents , Gamma scale: 351 cents ) into two equal parts, or ten equal parts of 35 cents each . This totals 34.29 steps per octave.
It may be derived from using 20:11 to approximate the interval 3:2/5:4[1], which equals 6:5 .
It was invented by Wendy Carlos.
More accurately the gamma scale step is 35.099 cents and there are 34.1895 per octave[1].
