Play Eine kleine Nachtmusik on Gesture Synth

Use an original G-major eight-target sequence—G, D/F-sharp, Em7, Cmaj7, then Am, D7, G/B and G—to compare inversion and seventh qualities while the left wrist moves between major and minor worlds.

Compare Four Voicing Types in a G-Major Night-Music Study

Mozart's public-domain serenade provides the name and historical context; the browser material is a new GestureSynth.me hand-control lesson. It does not reproduce the melody, score, ensemble parts, performance, recording, samples or a modern arrangement. The sequence is designed around four visible right-hand states: root-position triad, first inversion, minor or major seventh, and dominant seventh.

Unlike a route that repeats one cadence, this study places related qualities side by side. D/F-sharp and G/B both use two right-hand fingers but different left degrees. Em7 and Cmaj7 both use three fingers but different wrist worlds. Am and G both use one finger but sit on different degrees and worlds. Those controlled comparisons reveal which hand caused a mismatch.

Read the Voicing Sequence, Not a Melody Line

Section one is G, D/F-sharp, Em7 and Cmaj7. G starts with degree I, major wrist and one right-hand finger. D/F-sharp moves to degree V while two right-hand fingers request first inversion. Em7 moves to degree VI, rotates the wrist to minor and opens three right-hand fingers. Cmaj7 moves to degree IV, returns the wrist to major and keeps three right-hand fingers.

Section two is Am, D7, G/B and G. Am uses degree II, minor world and one right-hand finger. D7 moves to degree V, major world and four right-hand fingers. G/B returns to degree I with two right-hand fingers for inversion. The final G keeps degree I and major world while closing to one right-hand finger.

The sequence intentionally ends G/B to G. Because degree and wrist remain identical, the final task is a pure right-hand comparison between inversion and root position. Hold the left hand completely still. If the label changes root or world, the supposedly fixed hand moved or left the camera region.

  • Two fingers mean first inversion at D/F-sharp and G/B.
  • Three fingers create Em7 in the minor world and Cmaj7 in the major world.
  • Four fingers appear only at D7.
  • The opening and closing G states both use one finger, degree I and the major world.

Use Paired Comparisons to Find the Failing Hand

Compare D/F-sharp with G/B. The right hand uses two fingers for both, and the wrist stays in the major world. Only the left degree differs: V for D/F-sharp and I for G/B. Rehearse that pair outside the full route. If quality changes, improve the stability of the right-hand pair; if the root is wrong, rebuild the left-degree pattern.

Next compare Em7 with Cmaj7. Both use three right-hand fingers. Em7 needs degree VI and the minor wrist world; Cmaj7 needs degree IV and the major wrist world. Change the left degree first, then rotate the wrist. Keeping the right hand still makes it clear whether the live label is reacting to degree or world.

Finally compare Am with the two G states. All use one right-hand finger, but Am uses degree II and the minor world while G uses degree I and major. This is a useful reminder that a matching finger count alone never completes a target; the exercise reads the combined state.

Use the Section Break to Reset from Cmaj7 to Am

Cmaj7 ends section one with degree IV, major wrist and three right-hand fingers. Am begins section two with degree II, minor wrist and one right-hand finger. Use the manual break to close the right hand, prepare degree II and rotate the wrist. Select Next section only after the first Am pose is visible and separated from the other hand.

D7 is the only four-finger quality in the lesson. Approach it from Am in stages: degree V, major wrist, four visible right-hand fingers. Then move to G/B by returning the left degree to I and reducing the right hand to two while preserving the major wrist. Finish G by changing only two fingers to one.

The fixed 104 BPM click can help measure preparation gaps, but it is not a sequencer and does not represent the serenade's rhythm. The current target still needs roughly 350 milliseconds of stable recognition, followed by a 650-millisecond confirmation pause. Work with the click off whenever timing distracts from a clean comparison.

Verify Every Quality with a No-Skip Run

First test one valid target from each quality group: G for root position, D/F-sharp for inversion, Em7 for a minor seventh and D7 for a dominant seventh. Add the Cmaj7 comparison to prove that three fingers plus a major wrist produces a different family from Em7. For a boundary case, extend the right thumb on G and verify that the unwanted low octave prevents the normal target from confirming.

Restart after those tests and complete the eight cards without Skip. The ideal run has a stable two-finger right hand for D/F-sharp, a stable three-finger hand across the Em7-to-Cmaj7 world change, a prepared Am at the section boundary and a final G/B-to-G change made entirely by the right hand.

If labels flicker, separate the hands and improve front lighting before changing musical strategy. If matching is stable but sound is delayed, troubleshoot browser audio. Stop the session afterward so the camera track closes. Frames stay inside the browser tab, no microphone is requested and no performance video is uploaded.

Answers before you play

Eine kleine Nachtmusik Gesture Synth FAQ

Is this Mozart's original score or melody?

No. It is an original G-major gesture-control sequence in public-domain context. It includes no melody notation, ensemble score, recording, samples, accompaniment, performance or modern arrangement.

How do Em7 and Cmaj7 differ in the controls?

Both use three right-hand fingers. Em7 uses left degree VI and the minor wrist world; Cmaj7 uses degree IV and the major wrist world.

How do D/F-sharp and G/B differ?

Both use a major wrist and two right-hand fingers for inversion. D/F-sharp uses left degree V, while G/B uses degree I.

What should happen at the section break?

Release Cmaj7 and prepare Am with degree II, a minor wrist and one right-hand finger. The click remains paused until you choose Next section.
