Thankyou Matt, great advice! After playing for 50 years, I can easily follow this advice. Another benefit is reduced pain in my joints. Wow! Thanks again!
This will help me in teaching beginners a lot of things that I just take for granted. And I never realized moving my thumb could make barre chords easier, maybe that's why it took so long for me to learn... Also, I love the comedic relief! thanks so much
