| A '''prime interval''' is a musical interval which as a ratio of frequencies is a [[prime number]]; that is, a number such as 2, 3, 5, 7, ... which is divisible only by itself and 1. Any musical interval in the [[p-limit]] can be expressed in terms of a product of prime numbers less than or equal to p.

|
| The prime intervals are [[2/1]], [[1/2]], [[3/1]], [[1/3]], [[5/1]], [[1/5]], [[7/1]], etc.
| |
| The interval [[5/3]], for example, is not considered a prime interval.
