Two aspects working together in a song:
TEMPO, rhythm, repetition: The elevation of the mundane by the use of markers in time. By taking possession of time it stands still and becomes bulbous. resonant. radiant.
TEMPORAL, transient, narrative: without the temporal events that occur on top, below, inside, and throughout the rhythm/tempo, it would sooner or later become mundane itself. A bird sings, a car passes, a plate breaks. Trances fluctuate and everybody loves a good story.
The tempo without the temporal becomes an exercise in will.
The temporal without the tempo becomes an eye gazing only at itself.
All tempo is temporal, and when we look back we see that the temporal has a tempo.
