Advice on Banjo Back up Play Along CDs: some priorities
Good luck with the Backup CDs. Remember to read the instructions on charting out the chords and playing along with the tracks based on the chords and chord progressions. You could be missing the point of these practice cds (which is to work on many parts of your playing skills) if you obsess on the tab arrangements and don't just simply pick along, practice backup, up the neck, improvising and filling up the space when you forget where you are (which is gonna happen) does to everyone!
Start simple if need and build up to it.
