Boundary rules for the three domains
When does a musical behavior count as tonal, performative, or expressive?
Current position
OMAT assigns a behavior by its primary function in the musical act: organizing intelligible structure, realizing an action reliably, or shaping communicative meaning. The same event can involve all three; the rule prevents the domains from becoming exclusive personality types.
Practical implications
- Classify the function being examined, not the instrument or job title.
- Treat overlap as expected and make cross-loading an empirical question.
- Do not infer a permanent role from a relative profile share.
