The '''5-limit''' ~~~~(~~AKA~~ ''ya'' ~~~~in~~~~ [[color notation]]~~~~)~~~~ consists of all [[just intonation]] intervals whose [[ratio|numerators and denominators]] are both products of the primes 2, 3, and 5; these are sometimes called {{w|regular number}}s. The 5-limit is the third prime limit and is a superset of the [[3-limit]] and a subset of the [[7-limit]]. Some examples of 5-limit intervals are [[5/4]], [[6/5]], [[10/9]] and [[81/80]].

These things are contained by the 5-limit, but not the 3-limit:
