4/1, the 4th harmonic, double octave, perfect fifteenth, tetrave or quadruple, is the harmonic past 3/1 and before 5/1. It is the first composite harmonic, equal to a stack of two octaves: (2/1)2.
It can act as the interval of equivalence in temperaments that omit every other octave, such as meansquared.
