For me, I just automatically hear the low notes. I know people who can hear vocal harmony, all four parts. But for some reason I always hear the bass and the kick, or organ pedals, even the fundamentals in a motor sound as a car or truck goes by. The weight of it just draws me. The sound of pipe organ pedals in a huge cathedral just floors me. It must be DNA-based, I'm just wired for it.
Then on top of that, I'm 56, so I grew up listening to Top 40 AM radio, all the singles. So many radio pop / rock singles were done by session guys, mostly jazzers, who knocked out these little simple songs from their vantage point. It wasn't so formulaic in those days, the styles were still being born, the book was still being written. So I went to school on Babbit, Jamerson, Kaye, Osborne, David Hood, and on and on. Then blend in the the McCartneys and JPJones' and Entwistles and Squires, etc.
So I was obviously doomed from the start. When I first mastered David Hood's part in the Staples', 'I'll Take You There', it was just the greatest thing. There's been a lot of those since then (between trips to the clam buffet), and yet lots of disappointments that have often made me wish I'd become a plumber.
So I guess now I'm a recovering bassist.
