reduced harmonic
261/256, the vicesimononal comma, or the 29-limit ~sixth tone as is known in Helmholtz-Ellis notation, is a medium 2.3.29 subgroup comma. It is the amount by which 29/16 (the octave-reduced 29th harmonic) exceeds the Pythagorean minor seventh (16/9). It is significant in Helmholtz-Ellis notation and Functional Just System as the formal comma to translate a Pythagorean interval to a nearby undetricesimal interval.
