Aloha s,
If your musicians are ‘on the clock’ which means they are ‘sight reading’
then the better your score looks, the easier it will be for them to play.
Which means fewer takes and less $$$ spent on studio time.
If time is not an issue (they can have the score for a period of time
prior the the recording date) it won’t matter as much.
By then they will for all intent and purpose already have learned it.
Good Luck!
