Play Ding Dong Bell on Gesture Synth

Map the Eight Ding Dong Bell Gesture Targets

Section one is C–G7–C/E–F. Normal C uses degree I, the major wrist world and one right-hand finger. G7 changes the left hand to degree V and opens four fingers on the right. C/E returns to degree I but keeps two right-hand fingers for first inversion. F then moves to degree IV and returns the right hand to the one-finger triad shape.

Section two is Dm7–G7–low C–C. D minor seventh combines degree II, the minor wrist world and three right-hand fingers. G7 returns both the degree and wrist to the major route while opening four fingers. Low C and normal C then share degree I, major world and triad quality; only the configured right-thumb octave extension changes between them.

Say the control route before pressing Start: I major triad, V major seventh shape, I major inversion, IV major triad; II minor seventh, V major seventh shape, I low triad, I normal triad. Naming the implemented properties keeps this lesson grounded in the browser instrument rather than in lyric or melody recall.

• Target 2: degree V, major wrist and four right-hand fingers for G7.
• Target 3: degree I and two right-hand fingers for C/E.
• Target 5: degree II, minor wrist and three right-hand fingers for Dm7.
• Targets 7–8: release only the low-octave thumb extension.

Use the Confirmation Pause as a Clean Release Window

A correct state must stay readable for roughly 350 milliseconds. After the target locks, use the 650-millisecond confirmation pause to release the old right-hand finger count, preserve the visible left hand and prepare only the next property. This prevents G7 from flashing through an accidental inversion while the fingers close and makes the final low-to-normal C pair easier to observe.

Do not sweep the hands sideways to imitate two bells. Horizontal camera zones are not part of this preset. Keep both hands inside the guide frame with separated fingertips and a stable wrist angle. The exercise measures discrete chord controls, so a compact release followed by a compact re-entry is more reliable than a theatrical movement.

Prepare the Minor Seventh and Octave Pair at the Break

When F confirms, the section-complete screen pauses the practice. Before choosing Next section, form left-hand degree II, tilt into the minor world and show three right-hand fingers. That preparation isolates Dm7 from the preceding major triad. The optional metronome also stops at the break and cannot advance the next target for you.

For the closing pair, form normal C first and add the right-thumb low-octave extension for target seven. After it locks, hold degree I, the major wrist and one-finger quality still; release only that thumb extension during the confirmation pause. Repeat the pair until the displayed octave changes without the chord name or quality changing.

Use the Fixed 90 BPM Reference and Fix Misreads

Complete both sections once with the click off, then enable the built-in metronome. It starts after the first detected chord and remains at the song's fixed 90 BPM. The pulse is only a timing reference: it never confirms a pose, skips a target or crosses the section break. Restart it after Next section if you want the second half on the same reference.

If G7 reads as G, open four distinct right-hand fingertips. If C/E reads as C, preserve degree I and show two right-hand fingers. If Dm7 stays major, keep degree II while clarifying the minor wrist tilt; if it reads as D minor, add the three-finger seventh quality. If low C never changes register, extend the configured right thumb without changing the other properties.

Finish with one no-Skip pass focused on clean releases and one focused on the final octave pair. Count the run only when all eight targets confirm visually. This checks repeatable hand control in traditional context; it is not a rendition, transcription or evaluation of the original rhyme.
