5832/5831, the chlorisma, is an exceptionally small 17-limit (also 2.3.7.17 subgroup) unnoticeable comma of less than 0.3 cents. It is the difference between 18/17 and 343/324, and the difference between a stack of three 9/7s and 17/8.

In Sagittal notation, this is the default comma represented by two tinas.

Commatic relations

In terms of commas, it is the difference between the following superparticular pairs:

• 540/539 and 595/594
• 729/728 and 833/832
• 1701/1700 and 2401/2400
• 1716/1715 and 2431/2430
• 4914/4913 and 31213/31212

It factors into the following superparticular pair:

Temperaments

Tempering out this comma in the 17-limit results in the rank-6 chlorismic temperament, or in the 2.3.7.17 subgroup, the rank-3 chloric temperament. In either case it equates a stack of three 9/7 supermajor thirds with 17/8, the 17th harmonic minus three octaves. 80edo represents both 9/7 and 17/8 within 0.1 cents, so it and many 80th-octave temperaments temper out the chlorisma.

Etymology

The chlorisma was named by Jerdle in 2021. Despite the similar name, it has no relation to the previously-named chlorine temperament.
