ALLEGRO, in Music, an Italian word, denoting that
that the part is to be played in a sprightly, brisk, lively and gay manner.
Piu Allegro, signifies that the part it is joined to should be sung or played quicker; as
Poco piu Allegro intimates, that the part to which it refers ought to be played or sung only a little more briskly than allegro alone requires.
