Well as my story goes, on Wednesdays at 4:30, our band leader picks out two songs from a pretty large library that our band practices until 6:00 and we play at 6:30 for our youth group from church. I recently took the position on bass player in this band and last night was the fourth week I've played with them. The past weeks we had done songs with easy bass parts, for my sake so I could get accoustomed because I'm not that experienced, but last night we did one that had a more complicated line that was played twice at three spots: the intro, in between the chrous and verse 2, and before the bridge. Now within the 1 and 1/2 hours we had for practice I got both songs down pretty well and I nailed the line everytime when we played the song all the way through twice. Fast forward to praise and worship time and I botch the line 5/6 times. I don't know what it was, but you would think after a few weeks, I would be used to playing in front of about 70 people or maybe it was the pressure of doing a solo...of sorts or maybe I needed to practice it more. Either way, I think I was kind of nervous. That's how it would usually go though; I did better in practice than the preformance. Does anyone have any tips to prevent something like this from happening again, or just for playing live in general? As usual, all replies are appreciated.
