The blare comma is an unnoticeable 11-limit comma in the subgroup, with a size of only 0.078 cents. It is the interval in which twelve 9/7 septimal major thirds plus three octaves fall short by sixteen 11/8 undecimal major fourths.

It is named in analogy with the industrial theme of subgroup temperaments, "blare" being a word used to describe the loud and piercing noise of machines.

Tempering out this interval leads to the loudspeaker family of microtemperaments.
