Map the Eight A-Minor Gesture Targets

Section one is Am–E7–Am/C–F. A minor uses degree I in the minor world with one raised right-hand finger. E7 changes the left hand to degree V, returns the wrist to the major world and asks for four right-hand fingers. Am/C returns to degree I and the minor wrist, but two right-hand fingers make the inversion distinct from the opening triad. F then uses degree VI in the major world with one right-hand finger.

Section two is Dm7–C–E7–Am. Dm7 combines degree IV, the minor wrist and three right-hand fingers. C uses degree III in the major world and a one-finger triad. The last E7 repeats the earlier dominant target exactly, then A minor closes with the same complete state as target one. Those repetitions let you compare the opening and closing hand shapes instead of relying on sound alone.

Read all eight chord cards before pressing Start. Practise the two world changes Am-to-E7 and F-to-Dm7 without advancing, then rehearse right-hand counts one, four, two and one for section one. The sequence becomes manageable when degree, world and quality are prepared as separate properties rather than as one large memorised pose.

• Targets 1 and 8: degree I, minor wrist world and one right-hand finger for A minor.
• Targets 2 and 7: degree V, major wrist world and four right-hand fingers for E7.
• Target 3: keep degree I and the minor world, then show two right-hand fingers for Am/C.
• Target 5: combine degree IV, minor world and three right-hand fingers for Dm7.

Separate the Minor Home Chord from the Major Dominant

The most important transition is A minor to E7. Do not move both hands at once in a wide sweep. First form the new degree-V left-hand count, then make the major wrist orientation clear, and finally open four fingers on the right. On the return to Am/C, close the left hand to degree I, restore the minor tilt and show exactly two right-hand fingers. Small staged changes give the tracker fewer ambiguous frames.

A target must keep all four properties readable for about 350 milliseconds. When it confirms, use the 650-millisecond pause to name the next degree, world, quality and octave. Horizontal screen position does not select a chord. If E7 appears while you intend A minor, inspect the wrist world and finger counts before relocating your hands.

Use the Section Break to Prepare Dm7

After F locks, the exercise stops at the section-complete screen. Relax your hands, preview degree IV in the minor world and count three right-hand fingers for Dm7. Select Next section only after that shape is clear. The break is controlled by you; the optional click stops there and no target advances merely because time passed.

The Dm7-to-C change tests two properties at once: the left wrist returns to major while the right hand closes from three fingers to one. C-to-E7 keeps the major world but changes degree III to V and quality one to four. Repeat section two until those transitions are distinct, then restart the full lesson and compare the final A-minor state with the opening target.

Use the Fixed 72 BPM Reference and Fix Misreads

Complete both sections once with the click off. Then enable the built-in metronome, which begins after the first detected chord and remains at the song's fixed 72 BPM. It supplies a timing reference only; it cannot confirm a chord, skip a target or change the current section. Enable it again after Next section if you want the same pulse for targets five through eight.

If Am/C reads as A minor, preserve degree I and the minor wrist while separating two right-hand fingers. If Dm7 reads as D minor, show three right-hand fingers instead of one. If E7 reads as a major triad, open four fingertips clearly. If the camera target locks but sound arrives late, keep the correct pose and check the browser audio-latency guide.

Finish with three clean runs: section one alone, section two alone and the complete eight-target route. Count a run only when every target locks without Skip. The result measures camera-readable harmonic control inspired by a classical title; it is not a performance or transcription of the original piano work.
