Hi, can anyone tell me the standard format for notating upright slap bass. I can think of ways to do it but I want it to be the way that's professionally accepted. I know theres two different slaps sounds to notate, first the pulled string slap that has the pitch, but then there's the click when your hand comes back down to hit the strings. I can't use "x" headed notes for both. Do I say something like "slapped" at the beginning of the section of slapped notes, so then I use regular noteheads to indicated pulled string slaps and then do something like have "x" headed notes on the E, A, D, and G lines on the same beat for the click sound? How should I go about this?
