Assuming higher beat frequencies feel more agitating, we map temperament behavior to emotional descriptors for performance practice.
Low \(E\): tranquil/clear. Mid \(E\): luminous/urgent. High \(E\): dazzling or agitated (major), anguished or feverish (minor).
Bright-major “intense sunshine” has minor analogues: silver moonlight (low agitation), storm-lit melancholy (mid), and nocturnal fever (high).
