Although, tongue in cheek, the video below of Dave Grohl and Kyle Gass of Tenacious D teaches you more about the art of writing a big hook than a tonne of books you will ever read. Yes, there a huge amount of factors that come into play when it comes to writing a hit song, but the one that so many bands and artists neglect is the power of the hook.
A hook is simply the most memorable part of the song. Often, amateur songwriters forget that this is where they should be focusing. Not that fancy little verse or break you only hear for two bars. It`s all about the chorus.
Ever heard of the 80/20 rule? 80% of your success comes from 20% of your efforts. That 20% is all about the chorus. Get focusing on writing the catchiest, most memorable chorus you can and you will already be better than most artists out there.
The below video is hilarious as well as inspiring. Learn from the modern master of rock songwriting, Mr Dave Grohl.
