Though some of Vicentino's works survive in manuscript form as well as two volumes of five-voiced madrigals and a book of five voiced motets, his musical legacy and major contribution to the history of music is to be found in "L'antica musica ridotta alla moderna prattica." Within the body of this work is his argument for the progression of music away from the ancient church modes. Many were opposed to this type of thinking in music and Vicentino publicly aired this debate with Lusitano in 1551. Vicentino also argued forcefully for the use of chromatics and even discussed microtones in his discourse. It was because of the early arguments by Vicentino and other like-minded individuals that led to the development of consistent tuning and eventual temperament. "L'antica" promoted the ideas of Boethius when they agree with the position of Vicentino, and addressed vertical harmonies, enharmonic modes, a composing methodology and performance of these works on the arcicembalo. It would be interesting to discover what Vicentino's teachers and patrons thought of his ideas. The concepts certainly were not popular but being a student of Willaert and serving Ippolitto in Ferrara, Rome and Siena as well as serving as the choir master at Vicenza Cathedral, the impact Vicentino had on his contemporaries must have been similarly stimulating to them as his concepts were to the stimulation of new methods for musical composition. ~ Keith Johnson, Rovi
