== Application to fifthspan mappings == | |||
In any single-ring edo, a prime can be mapped not only to a specific number of edosteps, but also to a specific number of fifths. This is called the [[fifthspan]]. The fifthspan of prime 2 is always zero and the fifthspan of prime 3 is always one. The fifthspans of all the primes of interest above 3 is called the fifthspan mapping. The mapping can be expressed very concisely as a string of uniform solfege syllables in which -u/-o means aug/dim. Note that this often differs from the EDO solfeges listed above, where -u/-o often refers to up/down. | |||

Two edos can have the same mapping. For example both 19edo and 26edo are MaThoPaFla. | |||
Each prime has a second, larger fifthspan which is found by adding/subtracting the edo itself. For example, 31edo's prime 13 fifthspan is 15 but also 15 - 31 = -16. Thus 31edo's solfege string is also MaLuShoThe. | |||
In a multi-ring edo such as 72, the vowels must be repurposed to mean up/down. Note that this system fails if a ring has more than 13 notes, since there are only 13 consonants and one vowel for each ring. | |||

It's best to let -u/-o mean aug/dim not up/down, since the meaning of ups and downs changes in different edos. This picture shows the names if Da corresponds to the note C. | ||

Using movable-solfege, one can name the notes of a scale independently of the key. One can also name any physical interval on the lumatone. For example, one step in the 1:00 direction is always Du, two steps in the 2:30 direction is always Ma, etc. | |||

The placement of various primes on a Bosanquet keyboard is determined by the fifthspan mapping (see the previous section). Thus the solfege string tells a lumatone player the physical placement of all the primes of interest. | |||
