Play Vivaldi Spring on Gesture Synth

Map the Brisk Two-Section Target Route

Section one is G, C, D/F-sharp and D7. G begins on degree I with a major wrist and one right-hand finger. C changes only the left degree to IV. D/F-sharp moves to degree V and raises two right-hand fingers for first inversion. D7 keeps degree V and the major world while opening four right-hand fingers.

Section two is Em, Cmaj7, D7 and G. Em uses degree VI, the minor wrist world and one right-hand finger. Cmaj7 moves to degree IV, returns to major and shows three right-hand fingers. D7 uses degree V and four fingers. G closes with degree I, major world and one finger. Every target remains in the normal octave.

Rehearse the property changes away from the click first. The page confirms only after the requested combination remains stable for about 350 milliseconds. The short confirmation lock is preparation time, not permission to wave toward the next chord. Keep each completed shape visible until the active card clearly changes.

• G to C is a left-degree-only change.
• D/F-sharp and D7 share degree V but use two versus four right-hand fingers.
• Em is the route's only minor-world root-position target.
• Cmaj7 to D7 changes degree and right-hand count while preserving the major world.

Prepare Quickly Without Conducting the Beat

The 116 BPM click can tempt the arms into a conducting pattern, but arm swings do not select stored targets. Keep the palms in separate camera regions, wrists visible and fingers clearly separated. Form the next left degree first, set the wrist world second, then choose the right-hand count. That order makes an incorrect property easier to diagnose.

For D/F-sharp to D7, freeze degree V and the major wrist. Change only the right hand from two visible fingers to four. For Em to Cmaj7, set degree IV before rotating from minor to major and opening three fingers. If the label flashes through several chords, return to the last confirmed state and rebuild one property at a time.

Practise with the click off until every change is predictable. Then switch it on and aim to have the next pose ready during the 650-millisecond lock period. The beat does not grade rhythm and never forces an advance; accuracy remains the only success condition.

Compare the Inversion, Major Seventh and Dominant Seventh

Use D/F-sharp as the inversion checkpoint: degree V, major world and two right-hand fingers. D7 uses the same degree and world with four fingers, so the comparison isolates quality. Cmaj7 uses three fingers but moves to degree IV. Avoid guessing from the sound; read the live degree and quality chips before deciding what went wrong.

Run three representative tests. First change G to C without moving the right hand. Second change D/F-sharp to D7 without moving the left hand or wrist. Third move Em to Cmaj7, changing degree, world and quality together. For the boundary case, extend the right thumb on the final G and verify that the unwanted low octave is rejected.

If two and four fingers are confused, turn the palm toward the camera and fold unused fingers decisively. If Em remains major, correct the left-wrist world without changing degree VI. The exercise is designed so each failure points to a particular control rather than to vague musical timing.

Complete One Fast but Unrushed Pass

Restart and complete all eight cards without Skip. Confirm that the first G-to-C move is left-hand only, the D qualities are visibly distinct, the section break gives enough time to prepare Em and the last D7 resolves through a clear right-hand reset to G. Do not drop the hands until the completion state appears.

This is a browser-control study, not a violin lesson or transcription of Spring. The click supplies a neutral pulse and the target route supplies a coordination problem. You can slow down on the separate metronome page, but return to the fixed preset only when the poses remain readable at a brisk pace.

Use front light and keep both wrists in frame. If visual labels are stable but sound arrives late, diagnose the audio path. If labels are unstable, correct framing and separation. Stop after practice so the camera track closes; no microphone or uploaded performance is involved.
