What should I do with single fingerings on intervals / divided intervals, without knowing which note it applies to? Short of tracking down a cellist, is there a way I can identify them, or is there another way I should be approaching this?
I would have to say that asking a cellist would be the way to go if you are uncertain. If you’d like to send me an image of the passage in question, I can ask my cellist friends if you don’t know who to contact.
