RHY.6:4.2 - Construct a shared rhythmic correspondence

Align the relevant occurrences or phrase portions, then relate their positions under the source and target references. Preserve cycle identity and phase when later entry or coordination needs them. Carry duration, articulation, grouping or continuous course when the receiving operation consumes those features.

Choose a convenient shared description for the construction, such as ordered positions with event labels. It is a working intermediary whose fields come from this task, not a universal format for all rhythm.

For a duration-sensitive translation, align more than attacks. Locate where a sound continues across a beat, where it ends and where silence is prescribed. A printed continuation sign must retain that meaning in the receiving spoken or performed form. If the source has only attack labels, return duration as unresolved instead of inventing a sustained note or a rest.

When a source syllable names a sound class and the target names a beat position, derive the target sign from the event’s position. Preserve the sound class separately if needed. When a phrase maps to a learned instrumental realization, establish that phrase correspondence; do not manufacture a one-sign–one-stroke dictionary.
