MnemonicTriad quality = 3rd + 5th relationship
TheoryChanging one interval changes chord quality and function.
UseIdentify third first, then check fifth/seventh.
MnemonicMaj 4+3, Min 3+4, Dim 3+3, Aug 4+4
TheoryTriads define the basic harmonic identity in tonal music.
UseTrain all triads on one root, then transpose.
MnemonicNo third = no major/minor identity
TheorySuspensions create tension that often resolves to a triad.
UseListen for open, unresolved sound in progressions.

UseAfter triad match, test whether the seventh is major or minor.
MnemonicV7 wants to resolve to I
TheoryFunction explains movement, not just isolated chord labels.
