Map the Eight F-Major Gesture Targets

Section one is F–C7–F/A–B-flat. F uses degree I, the major wrist and one right-hand finger. C7 moves to degree V and opens four right-hand fingers. F/A returns to degree I while changing the right hand to two fingers for first inversion. B-flat then moves to degree IV and closes the right hand to the one-finger triad shape.

Section two is Gm7–C7–low F–F. G minor seventh combines degree II, the minor wrist world and three right-hand fingers. C7 changes to degree V, returns the wrist to major and opens four fingers. The last pair uses degree I, major world and one-finger quality twice; the low F adds the configured right-thumb octave extension and the final F removes it.

Rehearse the degree symmetry: I, V, I, IV; II, V, I, I. Then rehearse the right-hand counts: one, four, two, one; three, four, one plus thumb, one. The balanced returns are the lesson's practical focus. No attempt is made to encode the original melody or dance rhythm in those eight targets.

• Target 2: degree V and four fingers for C7.
• Target 3: return to degree I with two fingers for F/A.
• Target 5: degree II, minor wrist and three fingers for Gm7.
• Targets 7–8: preserve F and release only the octave thumb.

Keep the Tonic Returns Centred and Camera-Readable

F appears as a normal triad, first inversion, low triad and final normal triad. Because all four share degree I, avoid relocating the left hand whenever F returns. Hold the degree shape and let the right-hand finger count or octave thumb express the difference. This makes the exercise a useful test of independent control rather than a sequence of large whole-arm gestures.

Each complete state must remain visible for around 350 milliseconds. During the 650-millisecond confirmation pause, release the old right-hand property while keeping the left wrist in view. If both hands travel together, the detector may create a brief unintended degree. Horizontal camera position is not a chord lane, so centre both hands and favour clean finger separation.

Prepare Gm7 at the Section Break, Then Recover F

After B-flat confirms, the section-complete screen waits. Preview Gm7 before selecting Next section: form degree II, tilt the left wrist to the minor world and show three right-hand fingers. The pause prevents the major B-flat wrist from leaking into the new target. The metronome, if enabled, also stops and must be restarted intentionally.

Move from Gm7 to C7 by changing degree II to V, minor wrist to major wrist and three fingers to four. Then reset to normal F before adding the low-octave extension. After low F confirms, release only the thumb extension for the final target. A clean finish keeps degree, world and quality unchanged across that last register step.

Use the Fixed 96 BPM Reference and Fix Misreads

Complete one full pass without the click, then enable the built-in metronome. It starts after the first detected chord and stays at the song's fixed 96 BPM. It is not a waltz accompaniment and does not imply three target changes per bar. The target advances only after visual agreement, and the section break always requires the explicit Next section action.

If C7 reads as C, display four separated right-hand fingertips. If F/A reads as F, keep degree I and show two fingers. If Gm7 reads as major, clarify the minor wrist tilt; if it reads as G minor, add the three-finger seventh quality. If low F stays normal, extend the octave thumb without closing or moving the other fingers.

Finish with a degree-only pass, a right-hand-quality pass and one complete no-Skip run. Count the visual confirmations, not resemblance to a remembered orchestral phrase.
