I thought this wasn't true in 12TET, because in that case a perfect fifth interval is always a ratio of the twelfth root of two to power seven, or almost 3/2, no matter the starting point, C or E.
- klik99 2y agoSorry, that was an incorrect thing I was taught and I never checked it... The ratio of a perfect fifth in 12TET is always 1.498307, not exactly 1.5, but it's close enough to 3/2. The deviation from "simple ratios" is more or less depending on the interval (P5(3/2): -0.001692923, M3(5/4): 0.00992105, m3(6/5): -0.010792885).
