Hey Don, one other way to practice your foot and base button work without having to play the song on the treble side is to find a good recording on you tube that you can hear the seconds being played, and tap your feet and play your base buttons along with the song. Make sure your accordion and the accordion on the recording are built in the same key of course. And try to match which direction you need to be pushing or pulling according to the sound of the players melody, singing, and base buttons. Don't let yourself slip behind for another 4 years man!
