'''Charismic chords''' (formerly '''diasemismic chords''') are [[Dyadic chord|essentially tempered dyadic chords]] tempered by the [[charisma]], [[256/255]].


The [[diasemismic]] temperament contains many possibilities for essentially tempered dyadic chords including two triads and twelve tetrads in the [[17-odd-limit]] of the 2.3.5.17 subgroup.  
There are 2 triads, 13 tetrads, 17 pentads and 6 hexads as 2.3.5.17 subgroup [[17-odd-limit]] essentially tempered chords.


The two diasemismic triads are in inverse relationship:

Charismic chords (formerly diasemismic chords) are essentially tempered dyadic chords tempered by the charisma, 256/255.

There are 2 triads, 13 tetrads, 17 pentads and 6 hexads as 2.3.5.17 subgroup 17-odd-limit essentially tempered chords.

The two charismic triads are in inverse relationship:

  • 1–5/4–24/17 with steps of 5/4, 9/8, 17/12;
  • 1–9/8–24/17 with steps of 9/8, 5/4, 17/12.

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

  • 1–5/4–24/17–30/17 with steps of 5/4, 9/8, 5/4, 17/15;
  • 1–9/8–5/4–24/17 with steps of 9/8, 10/9, 9/8, 17/12;
