Hi All

I am a beginner and am going through the Basics course 1. I am stuck in the lesson https://www.guitartricks.com/lesson/31286 and the next one https://www.guitartricks.com/lesson/31287 where am not able to seamlessly change the chord from Em to C. C to Am works fine, Am to Em works fine. Is there a backing track for me which I can use to practice this change (or any for that matter)? Replaying the lesson from a specific point seems not to be working. 

Regards

Sabari
