| | The Bohlen-Pierce Site: 271 Tone BP Scale |
 | | The special status of mini-intervals in the order of 7 cents becomes obvious, and an equal temperament scale of 271 steps of 7.018 cents each is indeed a most exact approximation of all tones (enharmonics included) of the just BP scale, as shown above. |
 | | In just intonation, these steps are not equal, and a and b definitely are members of this group. |
 | | He lists two groups of scales with 43, 56, 69, 82 (the "n x 13 + 4" group) and 75, 88, 101 steps (the "n x 13 + 10" Group) respectively, favoring the 101-step version because it does for BP in terms of approximation accuracy what 53-step ET does for the traditional JI Western scale. |
