Play simple melodies(waltzes and two-step) like children songs and play along with the bass-side. After some practice you do it automaticly when you play, but it can take some time.

Yea that's what I'm doing. I knew there would be pot holes in the learning curve. I have a pretty hectic career. So i only get to practice an hour or so a day. But I enjoy playing. That's all that matters to me.

Bass side is awkward to learn. It took me 6 months to gain independence, and I'm still working to improve. Steve Riley calls it "your own personal rhythm section."

The better the bass side, the better you'll play the melody.
