# Ragismic chords

Ragismic chords are essentially tempered chords tempered by the ragisma, 4375/4374.

Since the temperament is complex, even the simplest ragismic chords are 27-odd-limit, although they contain only 7-prime-limit intervals. There are 6 triads, 21 tetrads, 22 pentads and 7 hexads as essentially tempered chords.

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

• 1-25/18-36/25 with steps of 25/18-28/27-25/18;
• 1-27/25-7/6 with steps of 27/25-27/25-12/7.

The inversely related pairs of chords are

• 1-9/7-25/18 with steps of 9/7-27/25-36/25, and its inverse
• 1-27/25-25/18 with steps of 27/25-9/7-36/25;
• 1-25/24-27/25 with steps of 25/24-28/27-50/27, and its inverse
• 1-28/27-27/25 with steps of 28/27-25/24-50/27.

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

• 1-28/25-36/25-14/9 with steps of 28/25-9/7-27/25-9/7;
• 1-27/25-25/18-3/2 with steps of 27/25-9/7-27/25-4/3;
