I am trying to setup an oratorio project intelligently.
In the original for the singers there exist 4 part books (CANTO, ALTO, TENORE, BASSO), each of them containing parts for the choirs and the solo parts for the arias.
It seems it was expected that a choir soloist would sing the arias - or even the choir part might have been sung by one singer only.
So I setup the Score in Dorico for the four singer parts to be a section (choir).
Now when it comes to the solo arias:
should I use the divisi function for the solo arias or
should I ‘change instrument’ to a solo singer (if that is possible)?
In a modern edition I would layout a complete score and a score with just the 4 singers (in one layout).
Thank you for suggestions.
