NOTATIO

Hi everyone,
I just signed up to this forum to ask this question. In the attached image there are a few places in the manuscript where the composer used a wavy line to indicate that the pattern should be repeated (or so I assume). I just don't get what c. B. stands for in the viola part...
Does anybody have an idea? For reference this is 'Abraham auf Morija' an oratorio by Joh. Heinr. Rolle. The manuscript is available on IMSLP.
Thanks for anyone that is willing to look into this. And I'm looking forward to being a part of this community.

"col" (with) or just "c" has been manuscript shorthand for centuries. I'm assuming here it just means the Viola continues the same line as the Basso Continuo group (Fondamento) but at the octave above as notated.

That makes sense. Thank you very much.
On the next page there are a few instances of c. VV. Or something that looks similar. Would that mean 'as above'?

That would be "col Violini" - with violins.

The symbol that looks like a trill squiggle finished off with an upward flourish is a "custos" which was usually used as a guide or warning at the end of the staff to indicate the pitch of the next note on the following line. Here it is being used to show the first note of the abbreviated groups.

Thank you very much.

You are very welcome, Bernd14. It's an interesting case.
