No, it's that \notes is identical to $notes (apart from the syntax) in that it creates a copy. So whenever you write \something and do something with it, whatever you do with it will not affect the original stuff stored in the Scheme variable something . Basically the idea is that you get a copy whenever you reference a variable, but the music passed around in expressions and from one function to another does not get copied unless you need more than one version of it.
Ah, that makes sense. Thanks! -- Aaron Hill
