1225/1224, the noema, is a 17-limit (also 2.3.5.7.17 subgroup) comma measuring about 1.41 cents. It is the difference between 35/34 and 36/35, and between 49/48 and 51/50.
In terms of commas, it is the difference between the following pairs:
- 273/272 and 351/350
- 325/324 and 442/441
- 375/374 and 540/539
- 385/384 and 561/560
- 595/594 and 1156/1155
- 625/624 and 1275/1274
- 715/714 and 1716/1715
- 833/832 and 2601/2600
- 1089/1088 and 9801/9800
It factors into the following pairs:
Temperaments
Tempering out this comma results in 18/17 being split into two equal parts, each representing 35/34~36/35, and enables the 25-odd-limit essentially tempered noemic chords.
