So what exactly does it take to write a hit song? Just 4 chords. So parents, save money on music lessons for your kids, just have them learn the four chords in this video and your kids could become your new retirement fund – best investment you’ll ever make:

The guy in the video is Benny Davis and he’s Australian – he and his two friends created a band/comedy act called Axis of Awesome and now tour the world.

BTW, the chords are I V VImin IV – so that could translate as D, A, Bm, G if you’re playing in the key of D – OR – E, B, C#m, A if you’re in the key of E.
