Learning guitar isn't easy, but there is no use in over-complicating it either. Learning easy guitar songs, or composing pop hits is even simpler. All you need to be able to play about 5,000 songs is 3-4 guitar chords. Most people I tell this are either surprised, or just flat out call me a liar... But I came across a great video on YouTube that demonstrates just this.
Have a go at this short flick and be amazed:
Pretty cool stuff there! If you just got the urge to compose the next hit of the century, grab a pencil and start writing the lyrics 🙂
