Translation of "solfeggio" into Portuguese

(music) a method of sight singing music that uses the syllables do (originally ut ), re , mi , fa , sol (or so ), la , and si (or ti ) to represent the pitches of the scale, most commonly the major scale. The fixed-do system uses do for C, and the movable-do system uses do for whatever key the melody uses (thus B is do if the piece is in the key of B). [..]
