'''4394/4375''', the '''Hebrewsma''', is a small 13-limit comma of about 7.5 cents.
'''4394/4375''', the '''hebrewsma''', is a small 13-limit comma of about 7.5 cents. When octave-reduced, 4394/4375 represents the difference between a stack of three [[13/10]]'s against [[35/32]].  


When octave-reduced, 4394/4375 represents a difference between a stack of three [[13/10]] against one [[35/32]]. Alternately, it splits the [[14/13]] in two parts, each corresponding to [[26/25]].
== Temperaments ==
Tempering out this comma in the 13-limit results in the rank-5 '''hebrewsmic temperament'''. Tempering it out in the 2.5.7.13 subgroup results in the rank-3 '''hebrew temperament'''. In either case [[14/13]] is split in two parts, each corresponding to [[26/25]].


== Theory ==
Tempering it out alongside with [[3136/3125]] sets the rectified hebrew temperament, which is a 2.5.7.13 subgroup extension of [[didacus]]. The presence of 4394/4375 being tempered out is the defining factor which specifies the temperament as rectified hebrew.

The comma is tempered out by the following vals: {{EDOs|72, 58, 53, 130, 111, 19p, 34d, 19e, 77, 38df}}. In addition, it is tempered out by [[353edo]], where it is connected to a proposal to reform the Hebrew calendar, hence its name.
