Cluster coordinate
Hear where notes live and where home is.
This territory connects pitch placement, interval shape, and the pull of a tonal center. The aim is not trivia: it is hearing a note clearly enough to make the next musical decision on purpose.
The capability this builds
Each concept below is one observable part of that capability. The route is guidance, not an unlock wall.

The territory
Every count below is scoped to this product. Open any node to see its actual exercise evidence and adjacent skills.
Foundation
Feeling the key, knowing which note "home" is in a passage.
Transfer
Hearing whether two pitches are the same, higher, or lower.
Transfer
Naming the distance between two pitches (third, fifth, octave, etc.) by ear.
Destination
Hitting a target pitch within tolerance, the foundation of singing in tune.
Suggested progression
Start at the foundation that feels useful. The sequence explains the relationship; it never blocks a concept.

Carry the first signal into another concept so the skill becomes flexible instead of memorized.
Open this stage03 · Apply
Use the same territory in a more complete decision where several signals must hold together.

Today’s plan chooses a reachable concept, records the evidence, and lets the next rep respond. The map is useful because practice comes back to it.
