Play Nutcracker March on Gesture Synth

Climb from C to G7 One Finger at a Time

Begin with C: degree I on the left, major wrist and one right-hand finger. For C/E, preserve the entire left-hand state and raise a second right-hand finger. For Cmaj7, continue to three right-hand fingers. The fourth target G7 finally changes the left hand to degree V while opening four right-hand fingers. This order exposes accidental wrist or degree movement because the first three cards should change only the right-hand count.

Pause after G7. The interface does not begin section two until you choose Next section, so use that moment to close the right hand to one finger and prepare degree IV for F. The first target of a section still needs the same approximately 350-millisecond stable match as every other card. Clicking quickly cannot bypass an incomplete pose.

Do one ladder-only rehearsal with the click disabled. Watch whether the label moves C, C/E and Cmaj7 without leaving degree I. If it changes root unexpectedly, restore the left-hand degree pattern. If Cmaj7 reads as G7 or another seventh, confirm the left degree and check that the fourth right-hand finger is folded until target four.

• C: degree I, major world, one right-hand finger.
• C/E: same left state, two right-hand fingers.
• Cmaj7: same left state, three right-hand fingers.
• G7: degree V, major world, four right-hand fingers.

Turn the Learned Counts into a Four-Chord Cadence

Section two is F, Dm7, G7 and C. F uses degree IV, major world and one right-hand finger. Dm7 moves to degree II, rotates the left wrist to minor and opens three right-hand fingers. G7 moves to degree V, returns the wrist to major and opens four fingers. C resolves with degree I, major world and one right-hand finger.

The Dm7-to-G7 transition is the densest change in the lesson. Move the left degree first, then set the wrist world, and finally open the fourth right-hand finger. On the return from G7 to C, reverse that process: choose degree I, keep the world major and close to one right-hand finger. Neither transition uses the octave thumb.

Avoid conducting the march with the forearms. Large swings can take fingertips out of frame and do not select a stored property. Keep elbows relaxed and let the hands perform compact, readable changes. The neutral click marks 108 BPM but supplies no drum pattern, ballet timing or accompaniment.

Check Finger Counts Without Guessing from the Sound

Use the on-screen match chips as the authority. A pleasing sound can still come from the wrong degree, world or quality, and the exercise will correctly refuse to advance. Count visible fingertips rather than relying on how open the hand feels. Keep unused fingers folded far enough that the model does not classify them as raised.

When two adjacent counts flicker, turn the palm slightly toward the camera while leaving the wrist-world tilt intact. If the left and right hands overlap, separate them horizontally without sweeping across the frame. If a hand disappears, return it to the camera region and wait for live labels to stabilize before correcting the target.

Complete three representative tests: C to C/E with no left-hand movement, Cmaj7 to G7 with both count and degree changing, and Dm7 to G7 with degree, world and count changing. Then include the boundary case: extend the right thumb during C and verify that the displayed octave changes, remove it, and confirm the normal C target instead. That test proves the lesson rejects an extra octave input.

Finish with One Unskipped Quality-Ladder Run

After isolated tests, restart the song study and complete all eight cards without Skip. Use the 650-millisecond confirmation pause to fold or open the next right-hand count before changing the left degree. At the manual section break, fully release the previous G7 shape, prepare F and only then continue. This prevents the dominant-seventh hand from leaking into the next section.

A complete run demonstrates command accuracy inside this browser instrument. It does not certify piano technique, recreate a staged performance or teach the original score. Players who want a slower pace can keep the built-in click off or use the separate adjustable metronome page before returning to this fixed 108 BPM preset.

Stop the session when practice is finished so camera tracks close. GestureSynth.me processes camera frames locally and requests no microphone audio. If sound arrives late while target matching remains stable, diagnose device or browser audio latency; if labels themselves flicker, focus on light, framing and finger separation instead.
