It's amazing how many "pros" I see in the audience from time to time. I'm working and they are paying to listen. I no longer get the feeling that most of them are looking down their noses, as they used to do.
Probably the reason is that they are used to hearing and/or using sequences, background recordings, karaoke, etc., and they don't have a clue what I'm doing. However when they get close enough or in position to watch, they usually ask for an explanation of the technology. Most are impressed.
Almost all assume that everything is pre-arranged or recorded. They have trouble with the concept of left-hand chords "calling the shots".
I've also noticed that if there is a guitar on stage, even if it's not being played, everything becomes more believable to them. In fact I would leave one there if it weren't for the fact that everyone who has ever picked up a guitar would want to "help" me. Not the real pros--the 99 percent who want to be!
