Here's a quick lesson where you can determine how well you hear and feel music. I play 2 examples of a song and explain the difference.

Bass part originally played by Carol Kaye, doubled by Lyle Ritz on upright bass. Ray Pohlman also plays mostly the same bassline on a Fender VI six-string bass guitar, sometimes up an octave and with some additional notes in the outro.

Find the complete song on YouTube. The sheet music is available through my website.
