I've got questions regarding playing with other musicians. I have a very good friend who plays sax and likes to jam with various other musicians and wants me to come and jam with them some time, but I've been telling him that I'm really not ready yet (and I really haven't been - I am a very new bass player and I have just recently reached a point where I can play along with certain songs on a cd) I've hung around plenty of this type of session and I know that sometimes by chance people will all know the same song, or if somebody knows a song - the others can usually figure something out - or else you may just pick a key and jam or jam a certain progression or whatever. (right?) So my questions for you more experienced players are: How will I know when I'm ready to play with other people (I'm feeling almost ready and guessing the answer is give it a try and see how it goes, but I dunno...) and the more important question, what should I work on to get there (I've been working on the 12 bar blues pattern and also trying to identify what notes are being played and follow the chords, even if I'm only playing roots) So when I do try to play with some other folks, I know that the drummer is what I focus on first and foremost and try to keep the rhythm tight with the drummer (right?) beyond that what approach might I take - I'm just looking to have a good time in a very informal jam session - advice?
