The '''ampersand''', or '''Ampersand's [[comma]]''', is the interval of '''34171875/33554432''' of size 31.567 [[cent]]s. It is the amount by which six [[16/15|classic diatonic semitones (16/15)]] fall short of a fifth; that is, (3/2)/(16/15)<sup>6</sup>. It also the amount by which 7 [[15/8]] exceed [[5/4]]. The [[5-limit]] temperament tempering it out gives the 5-limit version of [[Gamelismic clan #Miracle|miracle temperament]]. The Ampersand's comma was named after [[Paul Rapoport]]'s cat, Ampersand.
