what's a monzo?

named in honor of Joseph Monzo, a monzo is a notation for musical intervals which represents the interval as the exponents of each of its prime components

for example, the notation |a b c d e f …> is equivalent to the polynomial 2a ✕ 3b ✕ 5c ✕ 7d ✕ 11e ✕ 13f

this is useful for different approaches to musical analysis, such as color notation
