The 45 equal divisions of the [[4/1|fourth harmonic]] is a tuning system equvalent to 22.5edo, representing every second step of [[45edo]].
{{ED intro}} It is a tuning system equvalent to 22.5edo, representing every second step of [[45edo]].


Its step size is very close to the Alpharabian quarter tone [[33/32]]. In addition, it tempers out the tritrizo comma in the 4.7/6 subgroup, and along with it the [[quartisma]] in the 33/32.7/6 subgroup.
