I use to rely on printed music[charts]..
While working with a young lady...we would do maybe 300 songs.

One night , we were playing a job about an hour and a half away..I set up , and didn't have our music book..Oh well..we started out with songs I knew would be okay, and guess what, we could do all the material..

Charts act as crutches..if you are forced to work without them, you will be surprised to find you know the songs already..

I can still play songs I learned from fake books 40 years ago, while playing with my first 5 piece band..Standards just stay with you.. You may miss a chord change once in a while, but so what..

I haven't depended on charts now for more than 15 years..

Even new tunes , I can work out without the sheets.

I use to be a pretty good reader...I would imagine this skill may have diminished a little....but who knows, when I'll need to find out..

Lose the charts..you may be pleasantly surprised that you don't need them as much as you thought......They have become a security blanket more than a tool..
