'''625/624''', the '''tunbarsma''', is an [[unnoticeable comma|unnoticable]] [[13-limit]] comma with a value of roughly 2.77 [[cent]]s. Tempering out this comma not only equates [[25/24]] with [[26/25]]- splitting [[13/12]] in half and going part of the way towards splitting the [[9/8]] whole tone into three (the other comma that needs to be tempered in order to finish this job is [[676/675]])- but also equates [[39/32]] with the interval that results from stacking four [[5/4]] major thirds then octave-reducing.
