Italian operatic tenor, Marco Bordogni (1789-1856) received great success as a singer and teacher when he moved to Paris. His Vingt-Quatre Vocalises have remained popular, so much so that G. Armand Porret saw the need to adapt the studies for brass instruments. In Porret's arrangement, which is adjustable to C or Bb trumpet, cornet and saxhorn, a handy transposition table is included. The Vingt-Quatre Vocalises enable the performer to focus on tone, lyricism, articulation, dynamic contrast, fingering and breath control, among other significant aspects. Being notably versatile, and having remained a popular aid to vocalists and instrumentalists for over two centuries, it is clear that Vingt-Quatre Vocalises, adapted for C or Bb trumpet, cornet and saxhorn, would be a crucial aid to a performer's progression.
