Buzzard, ​48 & ​53, is a 2.3.7 temperament that splits 3/1 into four sharpened 21/16 subfourths. It can be considered the "simplest 2.3.7 temperament after Slendric" since it equates two (not one) 64/63's with one 49/48, exaggerating the difference between 21/16 and 64/49. Since Buzzard sharpens 147/128, equating it to an exact semifourth at -2 generators, it can be extended to 2.3.7.13/5 by equating 147/128 to 15/13, thus tempering out the huntsma, 640/637.
