The Pythagorean tuning is the 3-limit version of just intonation. It is the rank-2 temperament in the 2.3 subgroup that tempers out no commas. In other words, it is a trivial temperament.
See 3-limit for more information.
Scales
Because Pythagorean tuning is a rank-2 temperament, its scales can be named the same way scales corresponding to other rank-2 temperaments are, as follows:
- Pythagorean5 – proper 2L 3s. Also known as pythagorean pentic scale
- Pythagorean7 – improper 5L 2s. Also known as pythagorean diatonic scale
- Pythagorean12 – proper 5L 7s. Also known as pythagorean chromatic scale
- Pythagorean17 – improper 12L 5s. Also known as pythagorean enharmonic scale
- Pythagorean29 – improper 12L 17s
- Pythagorean41 – proper 12L 29s
- Pythagorean53 – proper 41L 12s
The hardnesses of the Pythagorean scales are about 1.442 for pentic, 2.260 for diatonic, 1.260 for chromatic, and 3.846 for enharmonic.
