Free online courseGuitar Music Theory Masterclass: Scales, Modes, Chords and Progressions

Course Description

Unlock the logic behind the fretboard with this free online masterclass in guitar music theory, designed for players who want to understand how scales, modes, chords, and progressions truly connect. Built for classical guitarists and curious musicians alike, it turns abstract concepts into practical insight you can apply to reading, composing, arranging, and improvising.

Start by solidifying the essentials: intervals, string relationships, octave shapes, unison notes, and the musical alphabet. From there, develop a clear map of the major scale, including patterns, positions, keys, and construction, so you can find notes confidently anywhere on the neck. You will also learn how triads are formed and transformed through inversions and shapes across string sets, then expand those ideas into harmonized major scale chords and functional progressions.

Move beyond basic harmony with 7th chords, drop voicings, shell voicings, and practical ways to recognize the key of a song from its chord movement. Explore chord families, suspended and power chords, slash chords, borrowed harmony, secondary dominants, blues progressions, non-diatonic options, and modulation to create more colorful musical stories.

Modes are explained in an organized, musical way, including how to think in series and parallel, how to choose mode sounds over different chord qualities, and how to craft modal progressions. Lead concepts continue with pentatonics, arpeggios, blues language, and advanced scale choices like melodic minor, harmonic minor, diminished and whole tone sounds, along with their harmonized chords. By the end, you will have a cohesive theory framework that makes the fretboard feel predictable, creative, and inspiring.
