I’ve decided to tweak my scores by adding more sordino directions so that players can prepare their instruments in advance, but I’m not entirely clear on what to write and where to write it, so I have a few questions:
Regarding instructions to put on the mutes, I’m thinking of adding “(to sord.)” after the final non-muted notes and then “con sord.” above the first muted notes. Is this appropriate?
Regarding instructions to take off the mutes, how should I handle this? I work with contemporary (film) scores, and I’ve only ever seen “senza sord.” used right as the non-muted passage starts, but Google tells me some also use “via sord.” right after the final muted notes to tell the player to remove the mute before the senza sord. passage begins. Should I use both of them, or just one? If so, which?
When the first passage of a score is played con sordino, but that muted passage only starts several bars or even pages later, should I add “(to sord.)” at the beginning of the score, or should I assume players will already be informed the first notes they play are muted?
Finally, do these instructions (placement, terms used, etc.) differ at all between different instruments and sections (strings, brass, etc.)?
