Say, as example, you've got a 2 bars pattern to play for twelve bars, how do you know the 12 bars is done and it's time for the change? I tried counting, not good as it remove all feel from my playing. So I rely on the singer, but sometime we practice and the singer's not there. So I end up messing up. Tried singing the song (as in lyrics)in my head, not good as I can't do 2 things at once and my bass playing suffers when I do that. So, I have the music sheet hidden somewhere, but reading really diminishes my interaction with the other musicians, not too mention that if I'm distracted for half a second, I loose where I'm at on the sheet and then I'm done for. So, how do you do it?
