Color notation tie-ins: -a = wa, -o = yo or zo, -u = gu or ru, and -i = ila. The zogu 5th is Sha because the -o and -u in zogu cancel to make -a. | |||

To find the octave inverse of any interval: | |||
* change the '''degree''' as usual: 2nd <--> 7th, 3rd <--> 6th, and 4th <--> 5th | |||
* change the '''quality''' as usual: major <--> minor, aug <--> dim, but perfect and mid are unchanged | |||
* change the '''vowel''' as expected: -o <--> -u, but -a and -i are unchanged | |||
For example, Fro = minor-Re-down becomes major-Ti-up = Tu. The rule for changing the quality means the ~4 and the ~5 must be either Fi & Si, or else Pi & Shi. The former is chosen because then the 6 mid intervals Ri Mi Fi Si Li Ti all use the default consonants. | |||
The 13 -a notes form a chain of 5ths running from the dim 5th to the aug 4th: | |||
Sha - Fra - Fla - Na - Tha - Fa - Da - Sa - Ra - La - Ma - Ta - Pa | |||
The aug 4th Pa is also the updim 5th Shu, which is the starting point for another 13-note chain of 5ths, all -u notes. Since Pu = Si, this leads to a 6-note chain of -i notes. This in turn leads to a 13-note -o chain, which leads back to the -a chain. 13 -a notes + 13 -u notes + 13 -o notes + 6 -i notes = 45 names = 41 notes with duplicate names for the 4 tritones. To summarize, the 4 vowels create 4 separate chains of 5ths, and the 4 tritones with duplicate names connect those 4 chains into one 41-note circle. | |||

As a result, it's very easy to find the note a 4th or 5th above any note. It always has the same vowel, and the consonant is as would be expected from conventional interval arithmetic. Thus Ra plus a 4th is Sa, Fro plus a 5th is Flo, etc. However the note a 5th above an aug or mid 4th would be an aug or mid 8ve, which don't exist in this solfege. Therefore one must rename the aug/mid 4th to a dim/mid 5th. Thus Po + 5th = Sha + 5th = Fra. Dim/mid 5ths may also need renaming: Sha + 4th = Po + 4th = To. | |||
A few minor exceptions arise with the -i notes. Conventionally, M7 + 5th = A4, and indeed Ta + 5th = Pa. But Ti + 5th = Fi not Pi. Likewise Fa + 4th = Tha, a minor 7th as expected, but Fi + 4th = Ti not Thi. These exceptions are not an issue as long as you remember that there is no Pi or Thi in the solfege | |||
The same rule for 4ths and 5ths also holds for plain major 2nds. Keep the vowel, and change the consonant as expected. Ra + M2 = Ma. Again, aug/dim intervals must be renamed: Po + M2 = Sha + M2 = Fla. But beware, this rule breaks down for major and mid 7ths: | |||
* Tu + M2 = Ri | |||
* Ta + M2 = Fru | |||
* To + M2 = Fra | |||
* Ti + M2 = Fro | |||
