Canto The canto (] ) is a principal form of division in a long poem. The word "canto" is derived from Italian word for "song" or singing; which is derived from the Latin "cantus", for "a song", from the infinitive verb "canere"—to sing. The use of the canto was described in the 1911 edition of the "Encyclopædia Britannica" as " a convenient division when poetry was more usually sung by the minstrel to his own accompaniment than read". There is no specific format, construction, or style for a canto and it is not limited to any one type of poetry.
