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

== 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.

=== Eagle 53 ===

==== By John O'Sullivan ====

O'Sullivan recommends readers to listen to his own compositions in Eagle 53 tuning, as he accurately follows the rules that he laid out for how to write with the tuning, meaning his works most closely reflect how the tuning is designed to sound.

~~# 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 following is O'Sullivan's playlist of 34 musical examples using the Eagle 53 tuning, including covers of some popular [[12edo]] songs, uploaded to his YouTube channel "@johnsmusic7". It is highly recommended for examples of 'what Eagle 53 sounds like':

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

* ''[https://youtube.com/playlist?list=PLfJh6Jy92I8k&si=diXOexJRrRR-_5W9 Songs in Eagle 53 tuning]'' -

~~# 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.~~

== ~~Relationship to~~ other ~~scales~~ ==

==== By other composers ====

Works by other composers may deviate from the rules of the tuning, so they are not recommended for getting an idea of 'how Eagle 53 sounds', however they are still valuable pieces of music worth a listen in their own right:

~~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.~~
