Fundamental Chords
If you're in NYC you should check out our in-person group classes! If you did you would spend about ten weeks working on strumming patterns and the chords that are featured in this 80 second video. Really take your time with these chords. Download the pdf and practice changing between them. You don't have to master them all before moving on but know that this is something that you'll have to come back to and practice a lot - chords are half the battle!
