How did you get started jamming and joining a band? Is there a minimum set of knowledge you think you should have before you're ready?
Like many people, it took me a long time to get going just because I didn't know anybody else who was playing music. Seriously.
I hacked a round a bit while I was in the Army (which was when I got my first bass) but it was sporadic and nothing lasted more than a few days due to the limited abilities of all involved.
Soon after I left the Army and came home to start college, I met a harmonica player at a blues show and started hanging out with him. He would get people to come jam in his garage, their incentive was alcohol and recreational drugs more than the music. It was still sporadic but it was a start playing with others, the typical experience of the guitarists showing me where to put my fingers and so on. Two years later, my college roommate was a banjo player so that started a period of intense bluegrass indoctrination along with another guy in the dorm who played guitar. A year later, I joined a bluegrass band comprised of other students leading to my first paid gig ($7.50 and free beer). Things progressed from there.
What was critical was
making connections with other players...this is also the single biggest problem
For any beginners out there, I would bet good money there is some group of people within a 10 mile radius of where you live that are so desperate for a bassist they would welcome you with open arms. How you
find them is one of the biggest riddles of the universe
Being pre-internet, for me that meant reading classified ads in the local papers or accidentally meeting someone who knew someone who knew someone, etc. Even today, most of my gig opportunities are still via word of mouth recommendations.
