'''Eagle 53''' is a [[Gallery of 12-tone tempered scales|12-tone tempered scale]] invented by [[John O'Sullivan | '''Eagle 53''' is a [[Gallery of 12-tone tempered scales|12-tone tempered scale]] invented by [[John O'Sullivan]]. | ||
== The scale == | == 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]]. ("Strength" according to the metric 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 metric 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 [[consonance]]s 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 a subset of [[53edo]]. | |||
Eagle 53's just version is identical to that of Euler's Genus Diatonico-chromaticum and Ellis' [[Duodene]], except that those used 45/32 instead of 7/5. | |||
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. | |||
