first, the rant: i can't sing. my voice is lousy, or so i've been told. i can't concentrate on the lyrics at the same time i'm playing. the drummer has a much better voice than me. why should i have to sing?
ok. anyway, the band expects me to sing. i can barely do about a girl and the chorus of long road to ruin. one of their complaints about their previous bassists was that they wouldn't sing. sooooooo, i'll be singing. i reeeeally need some tips on A: improving my voice. i may be expected to sing the fallsetto part on cemetery gates omg and B: some exercises to improve my multitasking ability. i've even tried humming
As for multitasking, it just takes practice, slow everything down and just concentrate on doing both at once, try not to worry about mistakes, it gets easier!
As for your singing... record it, listen to it... give it to us if you want advice!
