What’s challenging? What’s going well?
If you’re serious about learning chord backup, then be sure to take the last Chord Backup Workshop I gave. In it I suggested you learn just three chords and then practice chord backup on 10-20 songs. Doing that prepares you to understand theory.
Next month we’ll do another workshop on chord backup on April 8. Until then I encourage you share your questions, challenges and insights to this forum post.
