Let's talk about a common chord progression in Pop Music that is easy to learn and remember. The chord progression has just 4 chords. The 1st, 5th, 6th, and 4th chords in a Major key, played in that order. The "-" means minor. All chords in this progression are major except for the sixth, which is minor.
The above video goes through a bunch of Pop Music tunes that all share this same chord progression. It uses the key of D Major throughout. To play along, use the progression D A Bm G, these are of course the 1st, 5th, 6th, and 4th chords in the key of D Major.
