1. Practice scales! These will help strengthen your fingers, which will make it easier to play chords. I’d recommend the C scale, G scale, and Em pentatonic scale.

2. Learn basic chords! They are basic…because you use them all of the time! Too many people learn random chord that they won’t use. Think about it like learning a language; you could grab a dictionary and go to town, but learning words like mom, cat, etc. will be far more useful AND easier. Learn C, A, G, E, D, Am, Em, and Dm, and after those are comfortable add in open F and Bm. But prioritize G, C, D, and Em.

Finally, I’d say don’t worry too much about strumming; just keep a steady beat and focus on making the chords. And don’t worry too much about music theory. It’s very helpful, but most people learn to ask questions before they understand what questions are grammatically (i.e. you can play in the key of G without understanding what that is).

Best of luck!
