| Jun 6, 2020 at 18:08 | comment | added | Mark Wildon | One small nitpick: on my reading $q(a,c) = 7$ does not follow from the conditions: we could have $q(a,b) = 4$, $q(b,c) = 3$ but $q(a,c) = 1$. For example, take $(0,4,1)$, where $q(0,4) = |0-4| = 4$ (major), $q(4,1) = |4-1| = 3$, so this fits the definition of a 'major triad'. So I think we need to add $q(a,c) = 7$ to get triads in the required musical sense. | |
