Of course general solutions are better than specific ones. I was responding to an earlier comment of Perry's about the desirability of having a "higher level? way of encoding scordatura, etc. Let's say you encode the Biber violin sonata with scordatura so extreme the pitches of the open strings aren't even in order, but you don't realize that until later. Or maybe it's unclear what the intended tuning is, or (more likely) what string a given note is to be played on! It'd be nice to be able to describe the transposition of the A string in one place, not on every note that's played on the A string.
