I'm a 22-year-old bassist from Chile, and moving to the city to play jazz was the only way for me to play with real musicians. Since then, I've mostly been playing with my teacher or by myself with a metronome and backing tracks.
Today, I went to a bar to play at a jam session. I was really nervous, but I told myself it was okay and tried to relax.
When it was my turn to play, I said it was my first time, and they were cool about it. I suggested playing “There Will Never Be Another You,” but here's the thing: there was a vocalist, and she wanted to change the key from Eb to Bb. So I thought, “Fuck, I'll give it a try.” I opened iReal Pro, changed the key, and we started playing.
Man, I felt so bad about my playing. I couldn't really feel the band swing, and I think it was partly my fault. I lost track of the bars and the key. I'd never played a standard in a different key before, so I was kind of lost.
After that, the pianist told me to keep practicing. later i stayed listening to other musicians who play way better than me, wondering if I'll get another chance to play a standard I've actually been practicing, there was no, the jam ended, i only play one time.
I know I need to practice playing in different keys now, but for those of you on this subreddit who have experience with jam sessions, is there any other advice I should take with me for next time?
I'm planning to keep going, even though I'm feeling pretty sad and frustrated right now.
