'''7/1''', the '''7th harmonic''', is the [[harmonic]] past [[6/1]] and before [[8/1]]. It is two [[octave]]s above [[7/4]]. | '''7/1''', the '''7th harmonic''' or '''septuple''', is the [[harmonic]] past [[6/1]] and before [[8/1]]. It is two [[octave]]s above [[7/4]], and is the basis of [[7-limit]] harmony, as many 7-limit intervals can be expressed as the difference between this and another harmonic. | ||
7/1 is the fourth [[prime harmonic]], after [[5/1]] and before [[11/1]]. Many people consider it the first prime harmonic to be truly "xenharmonic", as it creates new interval categories not found in [[12edo]]. | |||
