ear training for sure.....the other thing isLet say someone in the band throws out a song to play and it's chords are pretty basic. Such as, E A and B but the chorus or bridge does an entirely different key/chords. Is there a "safe" place or key to play in if you don't know where to play. For example, you are invited on stage to jam and you need to come up with something on the spot.
that guys who jam, a lot have played over standards so often they can anticipate the changes......a lot of the chord structures are similar.....listen to and play through standards as much as possible,and learn to recognize 2 5 1's in every key 2 5 1's come up often........
