These fragmentary references to the activities of Tromboncino at the court of Mantua are indeed unsatisfactory, but they are about all that are within our reach. That he was born at Verona and that he was one of the most popular composers of the latter end of the fifteenth and the beginning of the sixteenth century and that his special field of art was the frottola are almost the sum total of the story of his career. We know that he wrote two sacred songs in the frottola style, nine "Lamentations" and one "Benedictus" for three voices. Petrucci's nine books of frottole (Venice, 1509) contain all of Tromboncino's. Carlo Delaunasy, a singer in the service of Isabella, Marchioness of Mantua in 1499, and Marco Carra, director of music to the Marquis in 1503, 1514 and 1525, are among the names unearthed from the archives of Mantua by their keeper at the request of Mr. Vander Straeten. These papers contained the names of a few other singers, players and directors, but their inadequacy was demonstrated by the fact that they contained no mention of Jacques de Wert, a composer of great activity and talent, to whom Vander Straeten devotes some fifteen pages of his exhaustive work. De Wert was born in Flanders near the end of the first half of the sixteenth century. While yet a child he was a choir boy in the service of Maria de Cardona, Marchesa della Padulla. Subsequently he entered the service of Count Alfonso of Novellara and in 1558 he published a book of madrigals which attracted widespread attention. Ten years later we find him at the court of Mantua, where his happiness was destroyed by the conduct of his wife. He appealed for aid to the Duke of Ferrara and the result appears to have been a dual service, for while he remained at Mantua he wrote much for the other court. His distinguished "Concerto Maggiore" for fifty-seven singers was written for some state festival. His service at Ferrara, whither he often went, enticed him into a relationship with Tarquinia Molza, a poet and court lady, which caused her to go into retirement. De Wert continued to live in Mantua and his last book of madrigals was published in Venice, September 10, 1591. He must have died soon afterward. Between 1558 and 1591 he put forth ten books of madrigals, generally for five voices, though toward the end he sometimes composed for six or seven. He was the author also of some motets, and Luca Marenzio, who brought the madrigal style to its most beautiful development and whose influence molded the methods of the English glee and madrigal writers, is believed to have been his pupil for a short time. Marenzio unquestionably lived for some months in Mantua, where according to Calvi[9] he completed his studies under the guidance of the Duke.
