RUN THE CHANGES

How to Practice with Run the Changes

Run the Changes is an interactive jazz vocabulary lab and transposition engine for players who want to turn harmonic knowledge into usable improvisational language. The tool now works through portable cells across single chords, major and minor ii–V–I cadences, dominant-function sounds, blues-dominant language, turnaround cells, rhythm changes fragments, static and sus vamps, modal colors, sequential cycles, symmetrical systems, and Woodshed signature vocabulary.

The focus is practical vocabulary. Each cell gives players a short musical idea they can hear, play, transpose, repeat, and eventually place inside real changes. Some cells outline classic ii⁷–V⁷–Imaj⁷ motion. Others isolate one dominant color, one modal sound, one turnaround shape, one rhythm changes fragment, or one modern intervallic idea.

Use it as a daily jazz improvisation practice tool: choose a harmonic category, select a cell family, pick a specific cell, listen to the contour, play it slowly, loop it with the metronome, then move it through several keys. The goal is to internalize sound, motion, time feel, and harmonic function until the language becomes available in real time.

Portable Jazz Vocabulary Cells

Run the Changes treats jazz language as a collection of movable cells. A player can shed one idea over Maj7, m7, dominant 7, altered dominant, sus, half-diminished, diminished, Lydian dominant, Dorian, quartal, or pentatonic harmony, then carry that same idea into tunes, standards, blues, rhythm changes, modal vamps, and original music.

The Woodshed Generator includes:

Single-Chord Vocabulary
Major ii⁷–V⁷–Imaj⁷ Cells
Minor iiø⁷–V7alt–i Cells
Dominant Function Cells
Blues-Dominant Cells
Turnaround Cells
Rhythm Changes Fragments
Static / Sus / Modal Vamps
Sequential / Cycle Cells
Symmetrical / Augmented Systems
Woodshed Signature Cells

This keeps the practice focused on flexible musical language instead of full-form chord drills. Players can work on the sound of a single chord, the motion of a cadence, the pressure of a dominant chord, the lift of a turnaround, or the logic of a cycle.

Built for Practical Transposition

The app is built for real players who need vocabulary to move quickly. C, B♭, and E♭ instrument formats are supported so players can practice material in the notation world they actually read. C instruments can work directly from concert material. B♭ trumpet, tenor saxophone, clarinet, and related instruments can use B♭ format. E♭ alto saxophone, baritone saxophone, and related instruments can use E♭ format.

The engine keeps the vocabulary portable. Players can practice a line in one key, hear it clearly, play it back, and then move it through the instrument until the shape becomes familiar in multiple registers and harmonic settings.

Woodshed Generator

The Woodshed Generator is the center of the tool. Choose a harmonic category, choose a cell family, then choose a specific cell. The available cells update from the selected category, so the practice path stays clear.

A player might choose Single-Chord Vocabulary and work on Maj7 guide-tone motion. Another player might choose Dominant Function Cells and isolate altered dominant language. Another might choose Rhythm Changes Fragments and work through I–VI7–ii–V7 cells. A teacher might assign one minor iiø⁷–V7alt–i cell in three keys. A working musician might use the generator before a rehearsal to refresh bebop, hard bop, altered, diminished, pentatonic, or side-slipping language.

Playback, Metronome, and Notation

Each cell appears in clean notation and can be played back with the built-in synth engine. Vibraphone is the default sound, with other playback colors available. The metronome supports slow practice, steady repetition, and gradual tempo work.

Every measure is kept rhythmically complete, with four beats per bar. Short cells and long cells are formatted so the notation, playback, and harmonic resolution line up clearly. Long ii⁷–V⁷–Imaj⁷ cells resolve into the tonic instead of leaving a final whole note stranded over the dominant.

For Students, Teachers, and Working Musicians

Run the Changes works as a jazz classroom tool, a private lesson resource, and a personal practice companion. Teachers can assign a category, cell family, specific cell, tempo, and key path. Students can log completed runs and track progress across practice sessions. Working musicians can use the generator to refresh vocabulary before rehearsals, gigs, auditions, jam sessions, transcription work, or writing sessions.

The tool supports players who are learning jazz vocabulary for the first time and players who already know the theory but want better command of sound, feel, and line construction.

Suggested Practice Routine

Start with one cell. Sing it before touching the instrument. Play it slowly with the metronome. Listen for the chord tones, guide tones, approach tones, and resolution points. Then move the cell through several keys.

For cadence cells, begin with C, then move to F, B♭, E♭, A♭, and D♭. Continue around the rest of the circle when the line feels stable. For single-chord cells, stay on one sound long enough to hear the color clearly, then transpose the same shape into other keys. For dominant cells, practice resolving each line to a major tonic and a minor tonic. For modal and sus cells, loop the sound until the phrase feels natural without needing a full chord progression.

The strongest practice happens when sound, fingering, notation, harmonic function, and time feel are learned together.
