Map the Repeated A-Major Pivot Route

Section one is A–D–A–E7: I–IV–I–V7. Section two is D–A/C-sharp–E7–A: IV–I in first inversion–V7–I. Normal A uses one raised finger on each hand, D uses four raised fingers on the left and one on the right, and E7 uses all five left-hand digits with four right-hand fingers. All three remain in the major left-wrist world.

A/C-sharp keeps the one-finger left degree-I pattern and major wrist world used by A, but the right hand changes from one raised finger to two for first inversion. Because the key, degree and world stay constant, target six is an exact test of right-hand quality rather than a new spatial chord position.

The exercise deliberately avoids a minor-world event so the faster pace can focus on repeatability. Use the same wrist orientation for every target and compare identical states: A at targets one, three and eight; D at targets two and five; E7 at targets four and seven. If a repeated state looks different, adjust framing before adding the click.

• Targets 1 and 3 are identical A states; repeat the same compact one-finger shapes instead of changing position.
• Targets 2 and 5 are identical D states with degree IV on the left and a one-finger triad on the right.
• Target 6 keeps degree I but uses two right-hand fingers for A/C-sharp.
• Targets 4 and 7 use all five left-hand digits plus four right-hand fingers for E7.

Make Every Return to A Visually Identical

Keep each wrist inside a stable camera-safe area and rebuild A with one raised finger on each hand. The system does not assign A, D and E to horizontal regions. A clean pivot therefore comes from closing the left hand to degree I, keeping the major wrist world and closing the right hand to the requested quality.

Hold every complete target for about 350 milliseconds. The 650-millisecond confirmation pause is preparation time: after D locks, plan the one-finger A state; after A locks, plan the five-left/four-right E7 state. Avoid moving until the confirmation feedback appears, because an early reshape can interrupt the hold.

Separate the A Triad From A/C-Sharp

Normal A and A/C-sharp share the same degree-I left hand and major wrist world. For A, show one right-hand finger. For A/C-sharp, keep the left side unchanged and raise two right-hand fingers. Hold the inversion until its quality indicator confirms before preparing E7.

Repeat section two to drill D–A/C-sharp–E7–A. This sequence moves from degree IV to degree I, expands to dominant degree V and closes at degree I. It also cycles right-hand quality one–two–four–one, making any skipped or merged finger count easy to spot in the match chips.

Use the Fixed 104 BPM Reference and Fix Fast Changes

First learn the locks with the click off. Then enable the built-in metronome, which begins after the first detected chord and stays at the song's fixed 104 BPM. The click does not advance a target and turns off at the section boundary. Choose Next section and enable it again if you want the reference for the second half.

If A/C-sharp reads as A, open exactly two right-hand fingers while keeping the left hand on degree I. If E7 reads as E, keep all five left-hand digits visible and separate four right-hand fingertips. If a label flickers at the faster reference, stop chasing the beat, finish the current camera match and use the separate metronome to build speed gradually.

A useful finish line is three deliberate passes: section one alone, section two alone, then the full eight-target route. Require every repeated A, D and E7 to lock without Skip. If section two fails only at A/C-sharp, slow down quality changes separately; adding larger arm motion will not improve degree recognition and can create extra occlusion.
