Figured it out. For those interested.
Rip the CD to your computer using Windows Media Player or whatever you use to ripp.
Download Audacity
http://audacity.sourceforge.net/
Open Audacity.
Click File -- Import -- Audio -- and this should take you to your ripped CD in your computer.
Pick a song - in this case - double click - 05 Adding the fifth.
Click view in the toolbar then click mixer board.
In the mixer board click solo then move the slider to the far left.
Now hit Play (the big green triangle)
Adjust the sliders so the piano is low and you can hear the bass line.
I'm not going to save the file as all I want is to hear the example, understand what is being done, and move on to the next example. Save if you like.
Have fun.
