The target order is C–G7–C–F, followed by C/E–Am–G7–C. In scale degrees that becomes I–V–I–IV, then I in first inversion, vi, V and I. C and F use the basic major-world quality, G7 uses four right-hand fingers and C/E uses the two-finger first-inversion quality.

Read each target as four properties rather than a chord name alone: left-hand degree, left-hand chord world, right-hand finger count and octave. Keep both hands at a consistent height so the volume remains even. A stable chord label is more valuable than reaching the next target early.

• C and F: basic major-world triads on degrees I and IV.
• G7: degree V with the four-finger dominant-seventh quality.
• C/E: degree I with the two-finger first-inversion quality.
• A minor: degree VI in the minor world with the basic quality.

Make Each Change Smooth Instead of Fast

Begin without the metronome. Hold C until the recognition label stops flickering, prepare degree V with the left hand and then open four right-hand fingers for G7. Return to C by changing both properties together, but keep wrist height steady so the transition sounds connected rather than accented.

When the first four targets feel repeatable, enable the 84 BPM click and change every second beat. Use the extra beat to prepare the next degree. Do not chase the click with a sudden arm movement; smaller finger and wrist adjustments give the camera a clearer sequence of landmarks.

Practise C/E, A Minor and the Final Cadence

Isolate C/E–Am–G7–C. C/E keeps degree I but changes the right hand to two fingers. A minor then changes the left hand to degree VI and the minor world while the right returns to the basic quality. G7 requires degree V and four fingers before C resolves the phrase.

Run this four-target group three times at half speed. Say the degree and quality silently before moving. If C/E becomes C, separate two fingertips clearly. If A minor remains in the major world, adjust the left-wrist mode before changing the degree. Reconnect the opening only after the cadence works cleanly.

Fix Recognition and Timing Problems

If the chord label changes when you raise or lower a hand, return both wrists to the centre of the camera frame and separate volume movement from chord-shape movement. Use a plain background, light the palms from the front and keep all fingertips visible. Slow recognition is usually easier to correct at 42 BPM than at full speed.

If the picture is stable but audio feels late, close heavy tabs, disable power saving and test wired headphones instead of Bluetooth. Camera landmarks are processed locally in the browser after Start; the exercise does not need a microphone, does not upload video and does not save a recording of the practice session.
