The Circle of Fifths - Music Theory

Welcome to this short lesson where we dive into one of the most mysterious and powerful tools in a guitarist’s arsenal — the diminished scale.

We’ll break down the two main forms of the diminished scale (half-whole and whole-half), explore how they relate to dominant 7♭9, 7#9 and diminished 7th chords.

The Harmonic Major Scale is a unique variation of the major scale, created by lowering the 6th degree.
