I'm just wondering how one would use solfège for chords/harmony. For example to sing C major does one say "do mi so"? If so wouldn't that in practice mean that one would have to say alot of words when harmonizing with another person? It's like arpeggiating the chord.
Instead of arpeggiating is there a block chord version that the entire chord is contained in one syllable. Or when we harmonize with solfege all notes of the chord need to be individually pronounced?
