Robert Tucci Sousapower Mouthpiece

Robert Tucci sousaphone mouthpieces offer a comprehensive selection of tested and proven tuba mouthpieces designed by and for professionals. The designers are you, the tuba players to whom the company listens. With each production sequence, all desired aspects of tonal color, response, dynamic, and factual range are implemented into every Tucci tuba mouthpiece. SOUSAPOWER 3, 4, 5, & 8 Designed for marching horns where projection is paramount, these heavy-shell sousaphone mouthpieces are open-blowing and deeply resonant. Reduced pressure enables a greater flow of air in a range where many mouthpieces choke up. Once the functional advantages are recognized, the upper middle and high registers of most instruments are more accessible, with a fine consistency of tone quality over a greater range. A unique balance between cup, shape, throat, and backbore dimensions assuring excellent intonation. The player’s firm embouchure interacts with and compliments the acoustical impedance generated in the instrument for optimal sound energy. High output results in efficiency and therefore ease of performance.  RT-SP3 Traditional Sound Cup Diameter: 32.00 mm. Medium-deep, pear-shaped.  Rim: 8.00 mm.
