Build useful harmony
Construct triads, seventh, suspended and added-note chords, then understand their inversions and harmonic jobs.
Move from knowing ingredients to shaping musical phrases.
This is the broadest stage of the curriculum. It connects keys with chord construction, fretboard systems with arpeggios, and rhythmic vocabulary with melody and song form.
After this stage
What will you understand and be able to do?
Create movement
Transpose ideas, phrase melodies, use syncopation, swing and blues vocabulary, and organise material into musical form.
Map the neck
Use CAGED and arpeggios to connect chord tones across positions rather than learning isolated boxes.

Topic map
How the lessons combine into larger skills.
Keys and chord language
Keys, the circle of fifths, triads, inversions, sevenths, functions and progressions.
Fretboard movement
CAGED, chord shapes, triad arpeggios, transposition and blues language.
Rhythm and form
Subdivision, syncopation, triplets, shuffle, swing, melodic phrasing and song structure.
With functional chords and confident phrasing in place, richer harmony becomes easier to hear as direction rather than jargon.
