In musical set theory, a pitch interval (PI or ip) is the number of semitones that separates one pitch from another, upward or downward. They are notated as follows: PI(a,b) = b − a For example C4 to D♯4 is 3 semitones: PI(0,3) = 3 − 0 While C4 to D♯5 is 15 semitones: PI(0,15) = 15 − 0 However, under octave equivalence these are the same pitches (D♯4 & D♯5, ), thus the may be used. (Wikipedia).

Pythagorean intervals in music and the magic of numbers | Maths and Music | N J Wildberger
Let's introduce the remarkable connection that the ancient Greeks, in the school of Pythagoras, discovered between ratios or proportions between small natural numbers and pleasant sounding harmonic intervals. The relation is perhaps best introduced by discussing notes on a guitar string,
