Map the Eight A-Minor Gesture Targets

Section one is Am–Em7–Am/C–F. A minor begins on degree I in the minor world with one right-hand finger. E minor seventh moves to degree V while retaining the minor wrist and opening three right-hand fingers. Am/C returns to degree I and uses two right-hand fingers for first inversion. F then moves to degree VI, changes the wrist to the major world and closes the right hand to one finger.

Section two is Dm–E7–low Am–Am. D minor uses degree IV, the minor wrist and one right-hand finger. E7 changes to degree V, rotates to the major world and opens four right-hand fingers. The last two targets return to degree I and the minor world with a one-finger triad; low Am adds the configured right-thumb octave extension, while the final Am releases it.

Memorise the wrist route separately: minor, minor, minor, major; minor, major, minor, minor. Then memorise the right-hand counts: one, three, two, one; one, four, one plus thumb, one. Separating these lists makes the slow practice precise instead of treating every dark-sounding target as the same hand pose.

• Target 2: degree V, minor wrist and three right-hand fingers for Em7.
• Target 3: degree I, minor wrist and two fingers for Am/C.
• Target 6: degree V, major wrist and four fingers for E7.
• Targets 7–8: keep Am stable and release only the octave thumb.

Build Quiet Holds Without Letting the Pose Drift

The 66 BPM reference leaves time to observe small mistakes, but tempo does not lengthen the engine's recognition rule. Every complete state still needs about 350 milliseconds of agreement. Keep the wrists at a comfortable angle and use the smallest finger-count change that produces the next label. Slow practice becomes useful only when the extra time improves stability rather than encouraging larger motion.

During the 650-millisecond confirmation pause, look at only the next degree and wrist world. Add the right-hand quality after the left hand is prepared. If the tracker briefly loses one hand, return it to the guide frame before forming the next chord. Horizontal travel does not select harmony, and lowering both arms does not create a softer dynamic in this preset.

Use the Section Break to Prepare Dm–E7–Am

When F locks, the section screen pauses both the target route and optional click. Before selecting Next section, tilt back to the minor world, form degree IV and use one right-hand finger for D minor. This reset keeps the major F wrist from leaking into Dm. The transition to E7 then changes all three visible properties and deserves a deliberate preparation pause.

For E7, set degree V first, rotate the wrist to major, and display four separated right-hand fingers. After confirmation, return to degree I and the minor wrist before adding the low-octave thumb extension. The final target keeps every Am property except that extension, so it is a controlled register recovery rather than a new chord search.

Use the Fixed 66 BPM Reference and Fix Misreads

After one clean no-click pass, enable the song metronome. It begins after the first detected target and remains at the fixed 66 BPM reference. It does not reproduce the sonata meter, arpeggios or expressive timing, and it cannot confirm or advance a target. Its purpose is only to reveal whether a stable gesture can be prepared on a calm, repeatable pulse.

If Em7 reads as E minor, keep degree V and the minor wrist while showing three right-hand fingers. If Am/C reads as Am, use two right-hand fingers without changing degree I. If E7 stays minor, clarify the major wrist; if it becomes E major, open four fingers. If low Am stays in the normal register, extend only the configured right thumb.

Complete section one while naming right-hand counts, section two while naming wrist worlds, then the full eight targets without Skip. These checks demonstrate camera-readable control of an original A-minor drill. They do not claim that the result plays, teaches or grades Beethoven's original piano work.
