⟨{{trim| 2: 13, 9: 41, 5: 30 }}][{{trim| 2: -4, 9: 2, 5: -1 }}⟩ = 13*-4 + 41*2 + 30*-1 = 0.

== Vals in regular temperaments ==

We write a tempered interval (an interval in a [[regular temperament]]) as a (generalized) monzo by taking a set of [[generator]]s (for rank-2 temperaments, this will be the period and the generator), then writing what JI ratio each generator approximates (distinguished from pure JI intervals by putting a tilde before it), followed by the number of that specified generator that the interval has. For example, the major third in [[meantone]] temperament can be written as {{monzo|~2: ‐2, ~3/2: 4}}, meaning "4 perfect fifths minus 2 octaves".

Similarly, edo tunings of a temperament can be given in terms of (a generalized version of) vals, by specifying how many edo steps are used for each generator of the temperament. For example, [[31edo]]'s tuning of meantone temperament can be written as {{val|~2: 31, ~3/2: 18}}.
