Bordogni Bordogni-Jacobs Wesley Jacobs, principal tuba (ret.) of the Detroit Symphony Orchestra edited this collection of Bordogni's vocalises for tuba. This Bordogni edition is the only complete version ever published for tuba. The music is carefully engraved to the highest quality standards. Many errors that exist in the old trombone editions have been corrected for this new book. Bordogni made his operatic debut at La Scala, Milan in 1813. He appeared in many of Rossini's operas on their first presentation in various towns and theaters. He sang for many years at the Théâtre des Italiens in Paris. He became a teacher at the Paris Conservatoire in 1820 and continued to teach there until shortly before his death.
