I think that it's important to "see" the harmony as well as hear it. I would be appreciative if the TB'ers that play Double bass or Electric bass would give their input. I've noticed from my own experiences, that now, when I'm playing jazz especially, I'm more cognizant of the chords. It seems to speed up the learning process. I'm aware that Jaco played piano, and I've seen Gerald Veasley in the studio with me lay down a guide piano track. I'm aware that Jack Dejohnette is a killer pianist. C'mon guys help me flesh this out... I'm also curious. Is it really possible to write songs that are "harmonically challenging" by just playing root movement or chords on bass? Songs make money, being a "bass hero" is somewhat antiquated, don't you think? Does the old adage that "knowledge is power" relate to being more than a bassist, to being...., more like a musician? (examples:McCartney, Sting, Jack Bruce) Thanks for all input.. and please, dig in with thoughtful commentary.
