And then there are those (like me) who cannot retain that information in full for various reasons(some medical), so I use charts, cheat cards, etc,....I have NO trouble interacting with the audience, as I do maintain a high degree of eye contact, even with the charts.

It can be done! I believe as always, that there is no wrong and right way, only "your way"...We each do whatever works for us.

Just because a player uses a chart makes them no less a muso, or entertainer.

Just my 2 cents
