The Parker Bel Canto has a medium shallow cup and is well-suited for chamber, solo and higher orchestra playing. This mouthpiece is ideal for Eb/F tubas and smaller 3/4 BBb and CC tubas. The tone is rich, focused and easily controlled. Fundamentals are centered with many additional tone colors and flexibility. The Parker Bel Canto is an excellent mouthpiece for solo literature and works like the Damnation of Faust, Petroushka and Mahler's First Symphony from the orchestral repertoire.
