3L1s<3/2> is constructed by repeating the fifth-spanning pattern LLLs of the ordinary diatonic mos (5L 2s) at the equave of 3/2. The so-called "Super Ultra Hyper Mega Meta Lydian" is one mode of this mos.

The notation "<3/2>" means the period of the MOS is 3/2, disambiguating it from octave-repeating 3L 1s. The name of the period interval is called the sesquitave (by analogy to the tritave). The generator range is 171.4 to 240 cents, placing it near the diatonic major second, usually representing a major second of some type. The dark (chroma-negative) generator is, however, its fifth complement (480 to 514.3 cents).

In the fifth-repeating version of the diatonic scale, each tone has a 3/2 perfect fifth above it. The scale has two major chords and two minor chords.

Angel is a proposed name for this mos. Basic Angel is in 7edf, which is a very good fifth-based equal tuning similar to 12edo.

Notation

There are 4 main ways to notate the angel scale. One method uses a simple sesquitave (fifth) repeating notation consisting of 4 naturals (eg. Do Re Mi Fa, Sol La Si Do). Given that 1-5/4-5/3 is fifth-equivalent to a tone cluster of 1-10/9-5/4, it may be more convenient to notate angel scales as repeating at the double, triple or quadruple sesquitave (major ninth, thirteenth or seventeenth i. e. ~pentave), however it does make navigating the genchain harder. This way, 5/3 is its own pitch class, distinct from 10/9. Notating this way produces a major ninth which is the Aeolian mode of Napoli[6L 2s], a major thirteenth which is the Dorian mode of Bijou[9L 3s] or an ~pentave which is the Mixolydian mode of Hextone[12L 4s]. Since there are exactly 8 naturals in double sesquitave notation, 12 in triple sesquitave notation and 16 in quadruple sesquitave notation, letters A-H (FGABHCDEF) or dozenal or hex digits (0123456789XE0 or D1234567FGACD with flats written C molle or 0123456789ABCDEF0 or G123456789ABCDEFG with flats written F molle) may be used.

Intervals

Generators	Sesquitave notation	Interval category name	Generators	Notation of 3/2 inverse	Interval category name
The 4-note MOS has the following intervals (from some root):
0	Do, Sol	perfect unison	0	Do, Sol	sesquitave (just fifth)
1	Fa, Do	perfect fourth	-1	Re, La	perfect second
2	Mib, Sib	minor third	-2	Mi, Si	major third
3	Reb, Lab	diminished second	-3	Fa#, Do#	augmented fourth
The chromatic 7-note MOS also has the following intervals (from some root):
4	Dob, Solb	diminished sesquitave	-4	Do#, Sol#	augmented unison (chroma)
5	Fab, Dob	diminished fourth	-5	Re#, La#	augmented second
6	Mibb, Sibb	diminished third	-6	Mi#, Si#	augmented third

Genchain

The generator chain for this scale is as follows:

Mibb Sibb	Fab Dob	Dob Solb	Reb Lab	Mib Sib	Fa Do	Do Sol	Re La	Mi Si	Fa# Do#	Do# Sol#	Re# La#	Mi# Si#
d3	d4	d5	d2	m3	P4	P1	P2	M3	A4	A1	A2	A3

Modes

The mode names are based on the species of fifth:

Mode	Scale	UDP	Interval type
name	pattern	notation	2nd	3rd	4th
Lydian	LLLs	3\|0	P	M	A
Major	LLsL	2\|1	P	M	P
Minor	LLsL	1\|2	P	m	P
Phrygian	sLLL	0\|3	d	m	P

Temperaments

The most basic rank-2 temperament interpretation of angel is Napoli. The name "Napoli" comes from the “Neapolitan” sixth triad spelled root-(p-2g)-(2p-3g) (p = 3/2, g = the whole tone) which serves as its minor triad approximating 5:6:8 in pental interpretations or 18:21:28 in septimal ones. Basic ~7edf fits both interpretations.
