Eagle 53: Difference between revisions

Line 1:

'''Eagle 53''' is a [[Gallery of 12-tone tempered scales|12-tone tempered scale]] invented by [[John O'Sullivan]]. It is a subset of [[53edo]].

== Conception ==

O'Sullivan designed Eagle 53 to meet the following criteria:

# Every note between 1/1 and 2/1, when paired with both 1/1 and 2/1 must make a high strength or medium strength melodic interval. ("Strong" according to the criteria described in ''Eagle 53 Article'' (2017)).

# The tuning must not have more than 12 notes per octave, so as to fit comfortably on small stringed instruments like ukeleles.

# There must be at least one good chord on each of the twelve notes. ("Good" according to the criteria described in ''Eagle 53 Article'' (2017)).

# These good chords must be playable on a fretted instrument such as a guitar.

The overall aim was to improve upon and replace [[12edo]], by making 12edo's consonances even more in-tune, at least in the most important keys, while also making available new exotic consonances and melodies which 12edo lacks.

Though it used a completely different ''methodology'' than a [[well temperament]], the ''philosophy'' behind Eagle 53 was similar to one. It is not a well temperament, but it achieves many similar aims to one.

== Relationship to other scales ==

Eagle 53 is identical to Euler's Genus Diatonico-chromaticum and Ellis' [[Duodene]], except that those used 45/32 instead of 7/5 in their just version.

This similarity is by coincidence and may simply speak to the fact that this is a useful and relatively simple scale that theorists are likely to land upon over and over, much like [[2L 3s]] or like 53edo itself.
