Naquian music

Tuning

Naquian music uses 7-tone scales rich in neutral thirds. Scales are abstractly viewed as subsets of a scale with 27 roughly equal steps per octave. The 3L 4s MOS scale (5 3 3 5 3 5 3) may be used, but they use other, non-MOS 7-note scales too. The quasi-equal 6L 1s MOS scale (4 4 4 4 4 4 3) in 27edo is mainly used as a reference point rather than as an actual musical scale, in that notation is based on the 6L 1s scale in the same way that Western notation is based on the diatonic scale.

Movement by one step of 27edo is usually avoided, since it is considered difficult to sing.

Historically other micro-divisions have been used or proposed - especially 27-well temperaments, 17-well temperaments or 17-equal.

Sjowaazheñ music

(Created by User:IlL)

Sjowaazheñ music is either monophonic or homophonic. Accompaniment, if present at all, is sparse and consists of only one voice (in addition to percussion).

Instruments

Some Sjowaazheñ instruments are the lute (ya'ook), various spike fiddles (shjhedgaañt), the lyre (biliiwid), various end-blown flutes (joweet'), a large drum (khool) and the woodblock (ghonyeeñ). String instruments usually are unfretted but marked at perfect fourths.

Tuning

The Sjowaazheñ tradition takes a purely melodic, rather than harmonic, approach to tuning, unlike the Talman and Bjeheondian traditions. Traditionally, the building blocks of Sjowaazheñ scales are tetrachords or pentachords, i.e. divisions of the perfect fourth into three or four intervals. Innovations over the years have led to finer divisions or "n-chords" of the perfect fourth being used in more "sophisticated" music. Nevertheless, steps in any n-chord are no smaller than about 50 cents.

The general term for an n-chord in Sjowaazheñ is hañbaac (pl. hañbaacin).

The octave may be divided into two perfect fourths plus one whole tone, to form an 'aañjh. However, in monophonic music, the perfect fourths divided into hañbaacin may even be stacked on top of each other indefinitely, without regard to octave equivalence, a practice called shiilyohookh. The same hañbaac or melody may be imitated a fourth above or below in this case. Or, the melody may be voiced in parallel fourths in an organum-like fashion (the only example of harmony in Sjowaazheñ music).

Etsoj Jopah analyzed hañbaacin in terms of rational divisions of string lengths. More recently, the theorist Wañjeyi proposed representing the Sjowaazheñ musical system by dividing the octave into 58 equal parts. One of his rationales was that the perfect fourth in 58edo is 24 steps, a highly composite number.

Some hañbaacin

There are some dozens of hañbaacin.

The numbers shown are approximate 58 equal temperament equivalents of step sizes.

Tetrachords

Sjowaazheñ tetrachords prefer to keep very large steps in the middle.

• beeky'ogh 'aad: 11 10 3
• beeky'ogh jyek: 10 11 3
• esyooñ: 10 10 4
• claañ: 9 8 7
• naajyetoh: 8 8 8 (similar to the equable diatonic genus)
• seeclaañ: 7 8 9
• bajiñd: 7 7 10
• slot'an: 6 6 12
• ookasdiñ: 3 19 2
• moc'aash: 2 11 11

Pentachords

• jook'etoh: 6 6 6 6
• yiisli: 7 6 6 5
• seeyiisli: 5 6 6 7
• jlatoñshah: 3 9 7 3

Rhythm

Sjowaazheñ music is typically unmetered, except ceremonial or military music. There is a smallest note length, and there may be small basic rhythmic figures in the melody, but the rhythms are not organized into measures. When percussion accompaniment is used, "small" percussion such as woodblocks may sound on each "beat" in the music. The drum marks the beginning and end of sections.

Notation

Much of Sjowaazheñ music was traditionally improvised. Sjowaazheñ notation works a little like unheightened neumes: it marks rhythm and rough melodic contours. The hañbaac to be used is also indicated. Much is left to the discretion of the performer, however.

In modern times, modern Talman staff notation (assuming a 58edo or 87edo framework) may be used, although this is often deemed less than satisfactory for Sjowaazheñ music.

Famous musicians and composers

• Gyaacl'osh: court composer, shjhedgaañt player
• Wañjeyi: theorist and composer

Hetomosphere music

Hetomic and Pelhyys music belong to the same Hetomosphere tradition.

Trây music

Trây music uses inharmonic quasi-equal tunings of e.g. 5, 7, 9, 13, 14 notes per octave. As such, inharmonic instruments like marimbas and metallophones predominate.
