Major rewrite. Removed superfluous text and tables (someone let me know if I went too far!), added an analysis as a circle of 5ths and as a chain of mid 3rds.

Andrew Heathwaite's solfege

Basic solfege

Andrew's solfege expands on the conventional Do - Di/Ra - Re - Ri/Me - Mi - Fa - Fi/Se - So - Si/Le - La - Li/Te - Ti - Do. Note that syllables usually treated as enharmonic equivalents become distinct pitches in 17edo. Note that Di (the A1) is wider than Ra (the m2).

solfege Do Ra Di Re Me Ri Mi Fa Se Fi So Le Si La Te Li Ti Do

Listed as a circle of 5ths: Se Ra Le Me Te Fa Do So Re La Mi Ti Fi Di Si Ri Li (Se)

The intervals run from dim5 to aug6. Note the strangely-spelled 5th from Li to Se (a double-dim 7th) that completes the circle.

Expanded solfege

To avoid naming ascending intervals as descending (e.g. Ra-Di or Me-Ri), 10 enharmonic equivalents are added, so that the 10 black keys each have two names. The 6 mid intervals use -u. The 4 half-aug intervals ^1, ^M2, ^5 and ^M6 use either -a or -o, whichever one doesn't conflict with a pre-existing syllable.
