'''Arithmetic pitch sequence of 715jot''' ('''APS715jot'''), also known as '''1 equal division of 715jot''' ('''1ed715jot''') or '''715-jot equal temperament''' ('''715jot-et'''), is an [[Equal-step tuning|equal-step]] scale with steps of 715 [[30103edo|jots]] (~28.50215 [[cents]]), or each 715th step of [[30103edo]].

APS715jot divides [[2/1]] into ~42.1021 equal parts, making it close to [[42edo]], but with [[pseudo-octave|impure octaves]] and better approximations of harmonics [[3/1]] and [[5/1]].

It is a kind of opposite twin to the scale [[APS720jot]], as they improve 42edo’s [[JI]] approximation by about the same amount, but in opposite directions (those harmonics which are slightly sharp in one are slightly flat in the other).

APS720jot’s step size is very close to that of [[42ed255/128]] and [[191zpi]].
