I’ve sung backups for many years and have been doing more lead singing lately. Singing while playing does not come naturally to me. There are a lot of factors that come into play for me. One is knowing the bass and vocal parts but there is also the simple aspect of being comfortable with your voice and how it sounds when you project it. It’s one thing to think you sound decent singing in the shower or along to the radio in the car, but when you’re belting into a microphone over a band it’s often an entirely different thing. I have a fairly limited vocal range and choosing songs that suit my voice is not always easy, so there’s that. Then there’s choosing the right key. What works when I’m alone in my music room isn’t always what works in a band context. Trial and error.
As for the physical side of playing and singing simultaneously, it’s not an all-or-nothing /you can do it or you can’t thing. Some songs are relatively easy to sing while playing and some are extremely difficult (from what I’ve heard even Sting would sometimes simplify his bass parts live) And at first everything will be difficult because you’ll be trying to focus on two things at once (and likely evaluating/critiquing two things at once, which adds a layer of distraction). The auto-pilot idea is legitimate to an extent, but it’s not as if you just end up focusing on one thing during performance - at least that’s not how it is for me. When I’m singing while playing my brain is ping-ponging between the two tasks. I’ll mostly be focused on the vocal but I keep checking in with the bass part, especially when I’m playing a variation or fill.
Start easy. Syncopation is the killer so choose a song with a line that consists of quarter or eighth notes only - at least when the vocals are present. One of the first songs I learned to sing and play simultaneously was Bill Withers’ “Who Is He And What Is He To You”. Go as slowly as you need to in order to get things right. It’s amazing what can be achieved with repetition at slow tempos. “Walking On The Moon” is an easy enough one to tackle because there’s not too much going on bass-wise that’s against the vocal. As you build your repertoire you’ll become more confident so keep at it, one song at a time.
