Definition of allegro. plural. allegros. : a musical composition or movement in allegro tempo.
All tempi are subjective to an extent (as far as beats per minute), are relative, and act as an indication of how to play the piece, aside from tempo. Try literally translating all of the various tempo markings from Italian, and see what you come up with. Allegro means happy or cheerful in Italian.
