GSMap the scaleGuitar fretboard

PTBuild the harmonyCmaj7

Listen, change, understand

One connected learning path

Theory becomes useful when every idea connects.

Move from the underlying pattern to the sound you want to make—without separating explanation from application.

Map the scale

See intervals and note relationships directly on your instrument.

Build the chord

Turn scale tones into triads, sevenths, inversions, and playable shapes.

Connect the harmony

Shape progressions with function, voice leading, rhythm, and melody.

Make it musical

Hear the theory in context and practice it inside a responsive jam workspace.

Built around your instrument

The same musical language, made tangible three ways.

Each instrument has four focused Labs that work together as a complete theory and practice environment.

Guitar Labs

Turn the fretboard into a map you understand.

Connect notes, intervals, chord formulas, and CAGED-style positions across the neck—then use them in progressions and jam sessions.

Scales & Modes

Map scale tones, modes, and melodic paths across every string.

Chord Theory

Build chords from intervals and compare practical fretboard voicings.

Chord Progressions

Develop harmony, voice leading, rhythm, and supporting melodies.

Jam

Practice ideas against playable forms, grooves, and chord changes.

G1C major across the neck

G2Cmaj7 open voicing

Piano Labs

See harmony laid out clearly at the keyboard.

Use the piano’s visual layout to understand scale formulas, chord construction, inversions, and smooth movement between harmonies.

Scales & Modes

Visualize scale formulas and keyboard paths in every key.

Chord Theory

Stack chord tones, explore extensions, and compare inversions.

Chord Progressions

Hear how voicings connect with intentional voice leading.

Jam

Apply harmony through accompaniment, improvisation, and repetition.

P1Cmaj7 chord tones

P2C – Am – F – G

Ukulele Labs

Learn the theory inside familiar, playable shapes.

Understand how re-entrant GCEA tuning changes scale paths and chord shapes while building a vocabulary you can put into songs immediately.

Scales & Modes

Trace notes and intervals through compact GCEA positions.

Chord Theory

Connect chord formulas to movable CAGFD-style shapes.

Chord Progressions

Arrange playable harmony with melody and rhythmic motion.

Jam

Practice chord changes and song sections in a focused workspace.

Don’t just memorize theory. Build with it.

Create progressions, shape melodies, compare voicings, save your work, and bring community projects into the Lab to understand how they are put together.
