Revision as of 22:30, 9 April 2022
In contrast to 12edo chords, 19edo has four instead of the usual two main tertian chord qualities which opens up completely new territory for eager musicians/microtonalists to explore.
19edo approximates intervals with factors of 2 (2/1), 3 (3/2), 5 (5/4, 5/3, 6/5) and 7 (7/6, 7/4, 27/14) quite well. This essentially means that normal chords – like in 12edo – can be represented nicely in 19edo.
Despite that enharmonics work differently in 19edo, pitches can be written down with standard notation.
Triads
Note that the cent values of the intervals are approximated. For detailed numbers, see 19edo.
| Chord name | Symbol | Steps | Cents | Audio |
|---|---|---|---|---|
| Major | C | 0-6-11 | 0-379-695 | |
| Minor | Cm, C- | 0-5-11 | 0-316-695 | |
| SuperMajor | Csmaj | 0-7-11 | 0-442-695 | |
| SubMinor | Csmin | 0-4-11 | 0-253-695 | |
| sus4 | Csus4 | 0-8-11 | 0-505-695 | |
| sus2 | Csus2 | 0-3-11 | 0-189-695 | |
| Diminished | Cdim, C° | 0-5-10 | 0-316-632 | |
| Augmented | Caug, C+ | 0-6-12 | 0-379-758 |
Tetrads (sixth/seventh chords)
Because of interesting new features – the supermajor seventh and "harmonic" seventh/augmented sixth – new tetrads are possible while existing ones can be preserved.
