I believe that, for this kind of mark spreading, one should use an app like Newzik, which was created expressively for this reason.David Ward wrote: ↑26 Sep 2023, 19:01 Can players using parts on iPads etc mark fingerings, bowings, breathings and all the rest in these? Or do they still have to rely on paper parts for that sort of thing? If iPad parts can be annotated in this way, when the string section principals mark the bowings before first rehearsal, how does this become available to the rest of the section? &c &c &c.
I don't use it too much, and even then only for in-person teaching, though I prefer other apps not created specially for sheet music.
ForScore seems to be the app of choice of "most people", though I don't like some parts of it and still prefer printed music for performance.
