# Charismic chords

**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;
- 1-16/15-4/3-17/12 with steps of 16/15-5/4-16/15-24/17;
- 1-16/15-5/4-4/3 with steps of 16/15-20/17-16/15-3/2;
- 1-16/15-9/8-6/5 with steps of 16/15-18/17-16/15-5/3.

The inversely related pairs of chords are

- 1-5/4-24/17-15/8 with steps of 5/4-9/8-4/3-16/15, and its inverse
- 1-4/3-3/2-15/8 with steps of 4/3-9/8-5/4-16/15;
- 1-5/4-24/17-3/2 with steps of 5/4-9/8-16/15-4/3, and its inverse
- 1-16/15-6/5-3/2 with steps of 16/15-9/8-5/4-4/3;
- 1-5/4-4/3-24/17 with steps of 5/4-16/15-18/17-17/12, and its inverse
- 1-18/17-9/8-24/17 with steps of 18/17-16/15-5/4-17/12;
- 1-20/17-5/4-24/17 with steps 20/17-16/15-9/8-17/12, and its inverse
- 1-9/8-6/5-24/17 with steps of 9/8-16/15-20/17-17/12.

For pentads, there are one palindromic chord and eight pairs of chords in inverse relationship. The palindromic chord is

- 1-5/4-24/17-30/17-15/8 with steps of 5/4-9/8-5/4-16/15-16/15.

The inversely related pairs of chords are

- 1-9/8-5/4-24/17-3/2 with steps of 9/8-10/9-9/8-16/15-4/3, and its inverse
- 1-9/8-5/4-24/17-15/8 with steps of 9/8-10/9-9/8-4/3-16/15;
- 1-5/4-24/17-3/2-15/8 with steps of 5/4-9/8-16/15-5/4-16/15, and its inverse
- 1-5/4-4/3-5/3-16/9 with steps of 5/4-16/15-5/4-16/15-9/8;
- 1-5/4-4/3-24/17-15/8 with steps of 5/4-16/15-18/17-4/3-16/15, and its inverse

- 1-16/15-5/4-4/3-3/2 with steps of 16/15-20/17-16/15-9/8-4/3, and its inverse

- 1-16/15-6/5-3/2-17/10 with steps of 16/15-9/8-5/4-17/15-20/17.

For hexads, there are two palindromic chords and two pairs of chords in inverse relationship. The palindromic chords are

- 1-9/8-5/4-24/17-3/2-15/8 with steps of 9/8-10/9-9/8-16/15-5/4-16/15;
- 1-5/4-4/3-24/17-3/2-15/8 with steps of 5/4-16/15-18/17-16/15-5/4-16/15.

The inversely related pairs of chords are

- 1-16/15-5/4-4/3-17/12-3/2 with steps of 16/15-20/17-16/15-16/15-18/17-4/3, and its inverse
