'''Major minthmic chords''' are [[Dyadic chord|essentially tempered dyadic chords]] in the [[13-limit]] rank-5 temperament, and in addition the rank-3 2.3.11.13 [[subgroup]] temperament, tempered by the major minthma, [[352/351]].

Major minthmic chords are essentially tempered dyadic chords in the 13-limit rank-5 temperament, and in addition the rank-3 2.3.11.13 subgroup temperament, tempered by the major minthma, 352/351.

There are 8 triads, 27 tetrads, 28 pentads, 12 hexads and 2 heptads as 2.3.11.13 subgroup 13-odd-limit essentially tempered chords.

For triads, there are four pairs of chords in inverse relationship:

  • 1–16/13–3/2 with steps of 16/13, 11/9, 4/3, and its inverse

For tetrads, there are five palindromic chords and eleven pairs of chords in inverse relationship. The palindromic chords are

  • 1–9/8–11/9–11/8 with steps of 9/8, 13/12, 9/8, 16/11.

The inversely related pairs of chords are
