2401/2400, the breedsma, is an unnoticeable 7-limit comma. It is the second smallest 7-limit superparticular comma, being the difference between 49/48 and 50/49, and between 49/40 and 60/49.


The breedsma is tempered out in the rank-3 breed family and all rank-2 breedsmic temperaments, all of which feature a neutral third interval for 49/40~60/49, and in which the classic chromatic semitone, 25/24, is split into two, each representing 49/48~50/49.


The corresponding temperament was named breed by Gene Ward Smith in 2004 after Graham Breed[1]. The term breedsma appeared shortly after[2].
