Courses
Structured lessons for learning fourths tuning guitar.
1.Orientation
Your first steps in fourths tuning.
2.First Sounds
Get playing immediately — chords, scales, and your first solo.
Your First Chords
Power chords, barre chords, and open chord shapes unique to fourths tuning.
Minor Pentatonic
The most important scale shape in rock, blues, and jazz — one box, three approaches.
Major Pentatonic
The bright counterpart to the minor pentatonic — same logic, different sound.
Pentatonics Everywhere
One shape, all keys — the payoff of fourths tuning.
3.The Major Scale
The foundation of Western harmony — shapes, intervals, and harmonization.
Major Scale Shapes
One shape, two octaves, and complete scale degree awareness.
Intervals on the Fretboard
Every interval has one shape in fourths tuning — the complete geometric map.
Harmonizing in Triads
Build a triad on each degree of the major scale — the I-ii-iii-IV-V-vi-vii° pattern.
Harmonizing in Sevenths
Extend triads to seventh chords — the foundation of jazz harmony.
4.Modes
Every mode of every parent scale — shapes, sounds, and applications.
Modes of the Major Scale
All seven modes — the sound, formula, fretboard shape, and musical context for each.
Modes of Melodic Minor
Essential jazz sounds — from the jazz minor itself to the altered scale.
Modes of Harmonic Minor
Classical minor sounds, Phrygian Dominant, and beyond.
Modes of Harmonic Major
The least-explored parent scale, full of unique colors.
5.Chord Voicings I
Shell voicings, drop 2, drop 3, drop 2+4 — building your harmonic vocabulary.
Shell Voicings
In ProgressThree-note voicings that are the foundation of jazz comping.
Drop 2 Voicings
In ProgressThe most versatile four-note voicing type — construction, inversions, and voice leading.
Drop 3 Voicings
In ProgressWider voicings with a different sonic character — when to use drop 3 vs drop 2.
Drop 2+4 Voicings
In ProgressSpread voicings with an open, orchestral sound.
6.Applied Harmony
Putting chords to use — progressions, voice leading, comping, and blues.
The ii-V-I
In ProgressThe most important progression in Western music — in every key, every voicing type.
Voice Leading Through Changes
In ProgressSmooth harmonic motion — minimal movement, maximum effect.
Comping Rhythms & Patterns
In ProgressThe rhythmic side of chord playing — feel, groove, and interaction.
Blues Harmony
In ProgressThe 12-bar blues in all its forms — basic, jazz, and minor.
7.Melodic Improvisation I
Your first solo vocabulary — chord tones, scales, approach notes, and superimposition.
Chord Tone Soloing
In ProgressUsing arpeggios as the foundation of melodic improvisation.
Chord-Scale Relationships
In ProgressWhich scale over which chord — the complete system.
Approach Notes & Enclosures
In ProgressChromatic voice leading into target notes — creating the bebop sound.
Pentatonic Superimposition
In ProgressUsing pentatonic scales over non-obvious chords for color and tension.
8.Chord Voicings II
Quartal voicings, clusters, upper structures, and triad pairs.
Quartal Voicings
In ProgressStacked fourths — native to P4 tuning, where open strings ARE quartal harmony.
Close Voicings & Clusters
In ProgressDense harmony — close position voicings and cluster chords.
Upper Structure Triads
In ProgressSimple triads over bass notes — creating rich, complex harmonies from simple shapes.
Triad Pairs
In ProgressTwo triads, six notes — systematic exploration of melodic and harmonic possibilities.
9.Melodic Improvisation II
Advanced melodic vocabulary — bebop, diminished systems, altered sounds, and beyond.
Bebop Language
In ProgressBebop scales, classic patterns, and the art of keeping chord tones on downbeats.
Diminished Scale Systems
In ProgressHalf-whole, whole-half, and diminished chord applications.
Altered Dominant Sounds
In ProgressThe altered scale, tritone substitution, and maximum dominant tension.
Motivic Development
In ProgressBuilding a solo from a single idea — telling a story.
Outside Playing
In ProgressDeliberate tension — sidestepping, superimposition, and controlled dissonance.
10.Chord Melody & Arrangement
Playing melody and harmony simultaneously — solo guitar mastery.
Chord Melody Fundamentals
In ProgressPlaying the melody on top of chord voicings — the basic principle.
Walking Bass & Chords
In ProgressCreating bass movement under chord voicings — two parts simultaneously.
Solo Guitar Arranging
In ProgressBuilding complete solo guitar arrangements from lead sheets.
Reharmonization
In ProgressCreating new chord progressions for existing melodies.
11.Advanced Harmonic Systems
Barry Harris, Holdsworth, symmetric scales, and deep quartal/quintal harmony.
Barry Harris System
In ProgressThe sixth diminished scale — one of the most elegant harmonic frameworks ever devised.
Holdsworth Approach
In ProgressScales as single entities, not patterns — the approach P4 tuning was made for.
Symmetric Scales
Whole tone, diminished, augmented — scales with built-in symmetry on a symmetric fretboard.
Quartal & Quintal Harmony Deep Dive
In ProgressAdvanced quartal and quintal applications — jazz, film scoring, and modern composition.
