The vavoom comma is a 5-limit comma, which manifests itself as the difference between a stack of seventeen classic diatonic semitones of 16/15 and a perfect twelfth of 3/1. Tempering it out in the 5-limit leads to the vavoom family of temperaments.
When it is viewed as a comma in the 16.3.5 subgroup, the vavoom comma is tempered out in 17edt, since one step of 17edt is very close to 16/15.
