Welcome to Key Signature Essentials! If you’re here, you’re likely interested in learning more about how the music you’re learning really works. Why do some chords sound better together than others?

This resource is heavily video based, with a couple of free PDF resources, so go ahead and get started by watching the overview videos above, and diving into each individual key in the videos below.
