I play a lot of songs where I don't come in for the first verse, or verse and a chorus, etc... Part of me wants to keep track of where I am in the song, so I sometimes "play along" through that part, but....with the volume control turned off on my instrument. It's a silent "noodle", and even at that I'm playing the part I would be if I was in at that point. There, Ive said it; I'm a silent/closet noodlist. Anyway, my first comment to an actual noodler would be "they're paying us by the hour, not the note" and see if he got the hint. The gigs I play, if you noodled, you wouldn't be asked back - noodling in a church service is just not done. We're there to create a mood, and noodling is not a technique that does that. While a bar band isn't exactly the same, you are there to create a mood (it's a different mood, but it's a mood), and again, noodling ain't a technique that'll ever help.
