What are the names of all the notes in a sol-fa scale, especially the chromatic notes between the basic Do, Re, Mi's.
per the first promising looking result from google...
[EDIT: from Wayback Machine]
Using sharps - Do, Di, Re, Ri, Mi, Fa, Fi, Sol, Si, La, Li, Ti, Do
Using flats - Do, Ra, Re, Me, Mi, Fa, Se, Sol, Le, La, Te, Ti, Do
There seems to be some (depending on country, author or whatever) variants of the general idea to replace vowels by higher sounding ones for sharps and by lower sounding ones (in extreme case always "u") for flats (which are also simply formed by attaching a "b" for "bemolle" in French, so si→sib).
In German wikipedia I found these replacements do→di, re→ri, fa→fi and so→si, for sharps , ti→ta, la→lo and mi→ma resp. ti→tu, la→lu and mi→mu.
English wikipedia article for Solfège also provides some ideas.
In moveable-do solfège, the usual practice is to indicate sharps with an -i vowel and flats with an -e or -a vowel. For example, a sharp do becomes di, flat sol becomes se, and flat re becomes ra.
There are chromatic variants of fixed-do solfège similar to the moveable-do system, but the usual practice in fixed-do is to sing the plain note name without alteration:
In the major Romance and Slavic languages, the syllables Do (Ut for the French), Re, Mi, Fa, Sol, La, and Si are used to name notes the same way that the letters C, D, E, F, G, A, and B are used to name notes in English. For native speakers of these languages, solfège is simply singing the names of the notes, omitting any modifiers such as “sharp” or “flat” in order to preserve the rhythm.
