Read the Eight Targets as Four Control Properties

Section one is F, C/E, Dm7 and C7. F uses left degree I, the major wrist world and one right-hand finger. C/E changes to degree V and two right-hand fingers for first inversion. Dm7 moves to degree VI, rotates the left wrist into the minor world and opens three right-hand fingers. C7 returns to degree V, the major world and four right-hand fingers.

Section two is B-flat, Gm7, C7 and low F. B-flat uses degree IV, major world and one right-hand finger. Gm7 uses degree II, minor world and three fingers. C7 restores degree V, major world and four fingers. Low F resets to degree I, major world and one quality finger, then adds the right thumb for the lower octave.

Name degree, world, quality and octave before forming each state. The interface needs the full combination to remain recognized for roughly 350 milliseconds. Once it confirms, keep the pose steady through the short lock period, then prepare the next state with the smallest necessary motion. A correct sound alone is not evidence that all four properties match.

• C/E isolates the two-finger inversion quality.
• Dm7 and Gm7 share the minor world and three-finger quality but use different degrees.
• Both C7 targets use the same degree, world and four-finger state.
• Only the last F extends the right thumb for a low octave.

Keep the Gesture Small Without Hiding the Fingers

A quiet musical idea does not require making the hands tiny or lowering them out of frame. Keep both wrists visible, separate the palms horizontally and use clear finger spacing. The left hand selects degree and major or minor world; the right hand selects root position, inversion or seventh. Volume follows vertical position, so place the hands at a comfortable middle height before refining the target shape.

For F to C/E, change the left degree and raise a second right-hand finger while preserving the major wrist. For Dm7, establish degree VI first, rotate into the minor world and then show three right-hand fingers. If the displayed chord flickers between families, freeze the right hand and correct the wrist world before attempting the complete transition again.

Front-facing light is more useful than dramatic low light. Avoid a bright window behind the hands and keep fingertips away from the image edge. If recognition becomes unstable when you try to play softly, restore a readable camera position first; the browser can synthesize a quieter result without sacrificing visible landmarks.

Compare the Two Minor Sevenths and the Repeated C7

Practise Dm7 and Gm7 as a controlled pair. Both require the minor wrist world and three right-hand fingers, so the only musical property that changes is the left degree: VI for Dm7 and II for Gm7. Hold the right hand and wrist steady while changing the degree. If the quality changes, the supposedly fixed hand was not stable.

The two C7 cards are intentional checkpoints. Use degree V, major world and four right-hand fingers both times. The first follows Dm7; the second follows Gm7. Repeating the same target after different minor-seventh shapes proves that you can rebuild one dominant state from two starting positions rather than relying on a memorized sweeping gesture.

For a boundary test, extend the right thumb on the first F and verify that the normal target does not confirm. Fold it, regain F, and reserve the low-octave command for the final card. This negative test confirms that the exercise is reading octave state in addition to chord identity.

Finish with One Slow, Unskipped Diagnostic Pass

Restart the exercise and complete all eight targets without Skip. Watch for a clean two-finger inversion at C/E, two distinct minor-seventh degrees, repeatable C7 states and a thumb added only on the final F. Use the manual section break to release C7 and prepare B-flat; the click pauses there and resumes only when you continue.

The successful result is a sequence of accurate control states, not a transcription or performance of Clair de Lune. The 68 BPM reference encourages patience but does not reproduce Debussy's timing. Turn the click off if it causes rushed shapes, then restore it after the eight target combinations are reliable.

If labels are correct but sound is delayed, investigate browser audio latency rather than changing the pose. If labels flicker, improve light, hand separation and camera distance. Stop the session when finished so the video track closes; frames remain in the browser, no microphone is requested and no performance is uploaded.
