A '''2-limit''' interval is either an integer whose only prime factor is 2, or the reciprocal of such an integer.  Naturally, since [[2/1]] is the octave, this limits us to unisons, octaves and stacks of octaves.  The 2-limit is fundamental to any sort of [[EDO]], and in fact, [[1edo]] is basically the 2-limit in full, only with additional temperament properties for other primes.

Due to [[Octave #Octave equivalence|octave equivalence]] the 2-limit is also very valuable as a transparent extension to various prime axes.
Due to [[Octave #Octave equivalence|octave equivalence]] as driven by pitch-chroma matching, the 2-limit also collapses very easily, with this collapse being generally implemented in lattices.  This collapse is helpful to understanding the pitches involved in other prime axes within the space of a single octave.
