Here is video Nr.2 in 2016. It is about playing chords.
The chords covered here are E minor, E major and A minor. You find more chords on the sheet I gave you. There is also a lot of free information on the internet if you want to find more chords.
The next chords (after the three covered here) I recommend learning are C major, G major, D major and D minor.
Next after that A major and B7.
With those 9 chords you could already play an enormous amount of tunes believe me!
Learn one a week and in a couple of month (or sooner) the world of songs is yours.
Again as ever the more you practice the easier it gets.
If you stick with it these chords will become second nature.
