A Dictionary of Music and Musicians/Do

DO. The syllable used in Italy and England in solfaing instead of Ut. It is said by Fétis to have been the invention of G. B. Doni, a learned Della Cruscan and writer on the music of the ancients, who died 1669. It is mentioned in the 'Musico pratico' of Bononcini (1673), where it is said to be employed 'per essere più resonante.'
