In contrast to [[12edo|12-EDO]] chords, [[19edo|19-EDO]] has four instead of the usual two main chord qualities which opens up completely new territory for eager musicians/microtonalists to explore.
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.


19-EDO 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 12-EDO - can be represented nicely in 19-EDO.

Because enharmonics work differently in 19-EDO, pitches can be written down with standard notation.
