Introduction: It's all about groove.
I play and teach bass. I do many different styles such as jazz, rock, metal, funk, country, soul, and even avant-garde, experimental and genre-crossing.
The way I play, the way I teach, is all about groove. It doesn't matter which style it is. If it feels good, it is good. The notes will come, the scales will come, the chords will come, but none of that matters if the feel isn't there.
I don't care what anyone says. The reason people dance, bob their heads, and move their arms in a hippie kinda way to music is because of the bass. The groove has to be there; play on!
