Five movements, five keys, both hands mapped — plus each chord's family, the leading tones that connect them, and a builder for writing movements of your own.
Grand — the practice voice. Every clumsy inner-voice jump shows.
Tap chords to add them to the timeline, hear them in any key, then copy the movement into your book. Every chip is a Tyson-quality voicing.
Tap keys to hold them down. The Lab names what you're holding, tells you its job in the current key, and shows what it's one note away from.
Try C, then E♭, G, B♭ and D — the Lab will call it Cm9 and tell you it's the 2 chord in B♭.
Sustain on = keys stay held so you can stack a chord. Sustain off = one note at a time, for picking out melodies by ear.
Write a top line over your movement. Pick a slot, then tap a note in the Chord Lab above — or use Send. Two slots per chord: one on the change, one on the "and."
The melody follows whichever movement is selected at the top. Notes inside the chord sound settled; notes just outside it create the reach.
| Amen Walkdown | 2 · 4 · 5/3 · 4/3 · 1/3 — the original. Bass leans down onto home. |
| The Lift | 2 · 4 · 6 · 1 — your requested family ladder. Every change keeps two notes and climbs. |
| The Drop-Down | Bass falls six steps: B♭–A–G–F–E♭–D. The classic Tyson drop-tone walk — the right hand barely moves while the floor descends. |
| The Tears | 4 · 4m · 1/3 · 2 · 1 — the borrowed-minor cry. One half step (the 3 falling) carries all the emotion. |
| The Climb | 1 · 1/3 · 4 · 5sus · 1 — bass rises while the hand holds. The 5sus proves the trick: same hand, new bass, new chord. |
Learn them in that order. Each one teaches a different way the bass can tell the story.
Chords are family when they share notes and share a job. Cm7 holds E♭, G, B♭ inside it — so the 2 and the 4 are brothers, interchangeable mid-sentence. G m7 shares three notes with E♭maj7 — cousins across the aisle. The 6 is the 1's relative minor: same notes, lights off.
Color chords (maj9, 6/9, 13, add2) aren't new chords at all — they're the same family member in different clothes. The function never changes; only the amount of light does. That's why the family panel groups them under one roof.
Practice: play a movement, then replay it swapping one chord for a family member. Same story, new shade.
Tyson's changes sound inevitable because the bass announces where it's going. A leading tone is a single note, played light on the last beat, one step (often a half step) from the next bass note: C–D–E♭, A–A♭–G, F–E–E♭, C–B–B♭.
Learn every movement back-to-front so each rep ends on the strongest ground. "Start from" sets your cell: Cell 1 is the last two chords; each new cell adds one chord earlier.
Key order: B♭ → E♭ → F → A♭ → D♭, roughly one per week, ending with the wheel drill — the full movement in all five keys, no stopping.
| 5 min | Cell drill in today's key and movement, Play button as your metronome at 50–60 bpm. |
| 5 min | Full run with leading tones on — eyes on the dots, not your fingers. |
| 5 min | Family swap or builder — replace one chord with a family member, or add one entry toward the book. |
Driving hours are ear hours: loop the recordings and sing the bass lines. You can't play a sound you haven't absorbed.
