Watch the Chord Formulas online guitar lesson by Matthieu Brandt from Chord Cookbook
Chords are derived from scales. The chords we will discuss here are all have a chord formula (1-3-5 for major chords, 1-b3-5 for minor chords, 1-3-5-b7 for dominant seventh chords,etc). These numbers refer to the distance that the note has to the root. In this section you'll get a breakdown of what these numbers mean and how a chord with a certain formula sounds. We continue with an overview of Open Position Chords.
