Map the Eight-Target D-Major Progression

Section one is D–A–Bm–F♯m. D begins on degree I in the major world with one raised right-hand finger. A moves to degree V while preserving the major wrist and triad quality. B minor changes to degree VI and the minor wrist world, still with one right-hand finger. F-sharp minor stays in the minor world but moves the left hand to degree III.

Section two is G–D/F♯–A7–D. G uses degree IV in the major world and one right-hand finger. D/F-sharp returns to degree I but uses two right-hand fingers for first inversion. A7 uses degree V, major world and four right-hand fingers. Normal D closes with degree I, major world and one right-hand finger, making the last three targets a quality-control cadence.

Say the degree route aloud before pressing Start: I, V, VI, III, IV, I, V, I. Then rehearse its wrist pattern: major, major, minor, minor, major, major, major, major. Separating those two memories prevents the long progression from collapsing into a series of vague hand locations.

• Targets 1 and 8: identical degree-I major triads for the opening and closing D.
• Targets 3 and 4: keep one right-hand finger while moving through minor-world degrees VI and III.
• Target 6: use degree I and two right-hand fingers for D/F-sharp.
• Target 7: use degree V and four right-hand fingers for A7.

Learn Degree, World and Quality as Separate Routes

During section one, the right hand remains a one-finger triad shape, so most of the work belongs to the left hand. Make the degree-VI B-minor pattern stable before tilting into the minor world, then preserve that wrist orientation while moving to degree III for F-sharp minor. A flicker back to major means the wrist changed with the finger count and needs a smaller motion.

Each complete state must remain visible for about 350 milliseconds. The 650-millisecond confirmation pause is long enough to recall only the next degree and world; save the right-hand quality check for the final moment. Horizontal camera position does not encode the progression. Keep the hands separated and let the explicit finger and wrist controls carry the memory.

Use the Section Break to Prepare the Closing Cadence

When F-sharp minor locks, the section-complete screen waits. Reset the left wrist to the major world and preview degree IV for G before choosing Next section. This deliberate reset separates the two minor targets from the all-major second half. The optional click stops at the boundary and cannot start the next target for you.

In section two, compare D/F-sharp and the final D. They share degree I and the major wrist, but the inversion uses two right-hand fingers and the closing triad uses one. A7 between them uses four. Repeat G–D/F♯–A7–D until the right-hand pattern one, two, four, one remains clear while the left hand moves IV, I, V, I.

Use the Fixed 84 BPM Reference and Fix Misreads

Complete the degree and world routes with the click off before enabling the built-in metronome. It begins after the first detected chord and stays at the song's fixed 84 BPM. The pulse never confirms a target or advances the section; it simply reveals whether your preparation fits a steady reference. At the section break, restart it after selecting Next section if needed.

If B minor or F-sharp minor reads as major, keep the correct degree count and clarify the minor wrist tilt. If D/F-sharp reads as D, show two separate right-hand fingers. If A7 reads as A, open four right-hand fingertips. When recognition is stable but sound is late, investigate browser output latency instead of exaggerating the gesture.

Finish with a memory test: complete section one while naming only degrees, section two while naming only right-hand qualities, and then all eight targets without Skip. A successful pass demonstrates that the chord properties are independently controlled. It does not claim to perform or transcribe the original Canon.
