Hi, I recently bought my first bass (Yesterday, as a matter of fact). I bought a five string Ibanez. I've been playing guitar for about two years and bass for about one day and two hours. Due to my guitar experience, I am fairly good at playing fingerstyle on the bass already. I'd like to begin jamming with two friends of mine, one who would be playing electric guitar and the other who would be spinning and scratching on turntables. The problem that I run into is I've never really played with other people before; I'm mostly experienced in playing songs by myself. Now, from what I understand the bass generally plays in rhythm with the drums and plays in the arpeggios of the root of the chord the guitar is playing. Is this correct? Also, what do I do if the guitar is not playing chords; if he is playing a lead melody? I plan on trying to jam with them this weekend if possible and would greatly appreciate any help that I can get about actually playing with others or on what I should focus on when practicing up until the jam session. Thanks in advance and I look forward to playing bass and participating in this forum.
