This chord is a game changer!! Why? Because as a beginner, you can learn G, Am, C, D and Em to be able to play almost any song in the world (as long as you put it in the key of G). The only problem is Bm. It’s a common chord when you’re playing in G and it’s the only one that is normally played as a barre chord. Barre chords are hard but now you have an option! Anytime you see a Bm, you can just sub this chord in and you’re all set! Finally, freedom to rock!
