I have been wrestling mightily with trying to figure out the proper score dynamic markings to use for situations that I have in my symphony-in-progress. Although only about two thirds of the first movement is done so far, these situations will be coming up again in the music yet to be written, so I thought this would be just the right place to seek some advice as I forge ahead.
Basically, what I'm looking for is the proper score markings that tell performers to play indicated passages about midway between the written dynamic and the one below it. For p I think sotto voce works fine for this, and would be clearly understood. I'm using poco f to indicate playing somewhere between mf and f. I think this would also be understood, but perhaps there's something better. The one I'm really struggling with is the indication to play between mf and mp. I can't really come up with anything that works, and I'm not getting any help from the glossaries of musical terms I've been searching. Any advice here would be most appreciated.
To follow up on the above, I also have a question about how I would indicate where performers resume playing at normal dynamics as marked. Do I simply repeat the dynamic marking without the modifier (for example p without the sotto voce)? Or is there another term I should use that says in effect "play normally"?
