...but manily bassists.
McCartney is the first to mind. And John Paul Jones. Who else?
It seems that it's usually pianists or guitarists who can jump around to other instruments. And...some of you are not going to like this...I do believe it's because those instruments allow for more musical knowledge. That's not to say bassists are LESS knowledgable, but it is possible to play "decent" rock bass without knowing a lot of theory. It's the bottom of the musical pecking order and most guys who go beyond it, move away from it.
Well, I refused to accept that. But instead of arguing, I went about learning. I already played drums and sang (did that before bass) but then I set out to play piano and then guitar and acoustic guitar. (And upright bass, harmonica, percussion and a little bad saxaphone). I think as a bassist it came naturally to me, yet I don't see a lot of other bassists who cross over.
And no need to talk about groove. Of course, that's what we do and that's what seperates us from guitarists. But still...you know what I mean.
Here's a little sample of some of my multi-instrumental playing. It's junky, fun 60's guitar instrumental stuff, but you'l get the idea.
Anyone else? Anyone play several instruments but just choose the bass as their main ax because, well..it is the coolest instrument of all.
