Build major, minor, diminished, and augmented triads from roots, thirds, and fifths. You will connect the sound of each triad quality to simple movable shapes on the guitar.

Play the same triad in different note orders and fretboard locations. You will use inversions to keep chord changes close instead of jumping around the neck.

Trace how one, two, or three notes move between chords while other notes stay in place. This chapter turns chord changes into visible paths for your fingers and audible motion for your ear.

See why Neo-Riemannian theory grew out of 19th-century harmony, chromatic music, and earlier Riemannian ideas about chord function. The chapter connects the theory to composers and later analysts without requiring classical-music background.

Use the three core transformations: P changes major to minor or minor to major, L moves by leading-tone exchange, and R moves by relative major or minor. You will play each move in several guitar-friendly positions and hear its distinct color.

Map P, L, and R as tiny fretboard motions instead of abstract labels. You will practice keeping two common tones, moving one voice by a half step or whole step, and choosing fingerings that make the transformation smooth.

Place the 24 major and minor triads into the Tonnetz, a map built from fifths, major thirds, and minor thirds. You will use it to see why close-looking moves often sound smooth and why distant moves feel dramatic.

Build short progressions by chaining transformations such as PL, PR, RL, and longer cycles. You will turn symbolic moves into playable guitar sequences, then compare the sound of different routes between the same chords.

Use Neo-Riemannian ideas alongside key centers instead of treating them as enemies. You will tell when a progression behaves like functional harmony, when it moves by smooth chromatic voice leading, and when both explanations help.

Apply transformations to common guitar idioms: open-position triads, barre chords, close triads on string sets, and partial chords. The focus is making Neo-Riemannian moves playable in real songs instead of only on paper.

Analyze short passages by marking triads, common tones, moving voices, and transformation labels. You will work with examples from classical music, film music, rock, metal, jazz-adjacent harmony, and game music where chromatic triads create color.

Use transformations to write riffs, loops, and chord progressions that sound smooth, strange, dark, bright, or cinematic. You will make small studies that start from one triad and grow into usable musical ideas.

Handle augmented triads, hexatonic cycles, and the famous three-major-three-minor worlds they create. You will see how repeated P and L moves produce symmetrical spaces that are especially useful for dramatic modulation.

Work with chromatic mediants: major or minor chords whose roots are a third apart and whose color often feels bold or cinematic. You will connect these moves to Neo-Riemannian paths and guitar shapes that make them easy to compose with.

Use Cohn-style parsimonious voice leading to compare chord moves by how little the voices travel. You will rank progressions by smoothness and use that judgment to choose stronger fingerings and better harmonic routes.

Extend the theory beyond plain triads with seventh chords, added tones, suspensions, and power-chord textures. You will keep the triadic core clear while adapting the sound to styles guitarists actually play.

Use transformational thinking for modulation: starting in one key area, passing through smooth triad moves, and landing somewhere new. You will design short bridges, pre-choruses, and cinematic transitions that change tonal center on purpose.

Create lead lines that follow the same voice-leading logic as the chords underneath. You will target common tones, moving chord tones, and chromatic passing notes so solos and melodies reinforce the harmonic motion.

Build a complete piece from a harmonic idea: choose a starting triad, plan a transformation path, pick guitar voicings, write a melody, arrange sections, and revise by ear. This chapter follows the full workflow from theory sketch to playable music.

Use diagrams, spreadsheets, notation software, MIDI, and fretboard apps to test transformations and document your ideas. The goal is practical support: faster mapping, clearer analysis, and better communication with other musicians.

Study full examples in depth, including how one passage can be heard through several valid lenses. You will practice explaining the musical effect, the fretboard choices, and the transformation path without forcing every chord into one rigid system.

Build advanced transformation networks with multiple routes, recurring motives, and large-scale harmonic plans. You will use these networks to analyze longer pieces and to design compositions that stay coherent while moving far from home.

Prepare a portfolio that shows skill: annotated analyses, fretboard diagrams, short compositions, recordings, and clear explanations of your choices. The chapter also points to theory communities, guitar paths, graduate-level topics, and ways to keep growing as a player, writer, or analyst.
