Adaptées ŕ la Trompette Ut ou Sib au Cornet et au Saxhorn-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 B' 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 apopular aid to vocalists and instrumentalists for over two centuries it is clear that Vingt-Quatre Vocalises adapted for C or B' Trumpet Cornet and Saxhorn would be a crucial aid to a performer's progression.
