Food industries include salted meat, sweets (torrone), vegetable oils, grana padano, provolone and "mostarda" (candied fruit in spicy mustard-flavored syrup, served with meats and cheese). Heavy industries include steel, oil and one electric plant. The river-port is a base for the barges transporting goods along the Po river. Music Cremona has a distinguished musical history. The 12th-century cathedral was a focus of organized musical activity in the region in the late Middle Ages. By the 16th century the town had become a famous musical centre. Nowadays there are important ensembles for Renaissance and Baroque music, i.e. Choir & Consort Costanzo Porta, and festivals which maintain Cremona as one of the most important towns in Italy for music. Composer Marc'Antonio Ingegneri taught there; Claudio Monteverdi was his most famous student, before leaving for Mantua in 1591. Cremona was the birthplace of Pierre-Francisque Caroubel, a collaborator with noted German composer Michael Praetorius. The bishop of Cremona, Nicolò Sfondrati, a fervent supporter of the Counter-Reformation, became Pope Gregory XIV in 1590. Since he was an equally fervent patron of music, the renown of the town as a musical destination grew accordingly. Beginning in the 16th century, Cremona became renowned as a centre of musical instrument manufacture, with the violins of the Amati and Rugeri families, and later the products of the Guarneri and Stradivari workshops. To the present day, their handmade work is widely considered to be the summit of achievement in string instrument making. Cremona is still renowned for producing high-quality instruments, rare examples of which can be seen when visiting the local Museo del Violino.
