"Do you mean that the notes you are articulating are the melody notes - and the rolls are a fast little envelope for each melody note...."Well put Marion. Yeah, something like that. Bit of a can of worms I've opened. I just got my guitar to see if I was explaining it correctly...and the answer is "Yes....and No".
Let's wait til Peter T sees this. he makes his living explaining things. Trust me, if you were sitting in this room I could show it to you in five minutes!
The problem is that there are more variables than I mentioned. All of which are neccessary in order to use it as a complete accompaniment.
Sorry to be so confusing. If I drank, I'd need a drink!
