24edo/Interval names and harmonies: Difference between revisions

Line 54:

Neutral intervals basically are right between the major and minor version of an interval in 12edo. For example, the neutral third is between the major and minor third. The name also suggests that the interval can function as either depending on how it is used. In addition, neutral intervals contain very special color to them that makes them unique.

=== Ultramajor/~~Inframior~~ ===

=== Ultramajor/Inframinor ===

Ultramajor and Inframinor are used to describe major and minor intervals which have been modified by a quartertone away from the neutral position. Only seconds, thirds, sixths, and sevenths have ultramajor and inframinor classes

Line 132:

Like with the augmented chord, the diminished chord in 24edo has a wider variety of set-ups and follow-ups than in 12edo.

== ~~Other~~ types chords ==

== Rules for finding other usable chord types ==

In addition to the types of basic chord, one can derive other types of usable chords, through a set of rules known as the "Dinner Party Rules"<ref>[https://www.youtube.com/watch?v=A355E0MKw7A Quartertone Harmony - The Truth About Quartertone Chords SD 480p]</ref>...

* Every chord must be comprised of a chain of "friends" in which each note is a "friend" to every other note; a "friend" is defined here as a note separated by either a major third, a minor third, a neutral third, an inframinor third, or an ultramajor second.

* No note can have an "enemy"; an "enemy" is defined here as another note in the chord separated by either an ultraprime, an inframinor second, an infraoctave, or an ultramajor seventh, with the intervals of an ultramajor third, an inframinor sixth, a paraminor fourth and a paramajor fifth also making this list in the majority of cases.

* No crowding; specifically, no note can have more than one other note closer than a major second.

Once these rules are taken into consideration, finding usable chords and chord progressions is considerably easier.
