My newbie band has been around for about half a year now and only recently we've finally managed to get a singer, and I've ran into some unforseen trouble with that. It seems that on some songs, the vocal part throws me off my timing. For example - All The Small Things. Yeah I know, boring, super-easy bass part. I agree, and I use to ace it when we were playing just the 3 of us, me and 2 guitarists, plus a drumming machine. Really easy to steadily play the notes and switch on time. Now the singer not only sings it differently from the original (timing-wise), she also sings it differently each time. Pretty much random timing of the words. And that just throws me off, and I can't feel the bar changes anymore because I listen too much to the words. Like the part "Say it ain't so, I will not go...", it's supposed to be all eighth notes, 2x C, 1x G and 1x F, and I get lost, and usually switch one eighth note too soon or too late. So how to solve this? Try to focus more on my bass sound and block out everything else? Foot tapping? Counting 1234? Practicing the whole thing on my own hundred times in a row until it's completely automatic?
