In my playing, I realize that I am the rhythm of the song. At least in church where I play. Bass is rhythm, drums is beat, organ is harmony. Without the bass, there really isn't that much rhythm, aside from the beat of the drums. There have been times when I was playing that I abandoned playing rhythm to play a melodic content, but after a few seconds, the song felt empty and I quickly returned back to my rightful role as the rhythm. My question is, where does melodic bass playing fit into a song, if we are the rhythm section?
