With the introduction of the baritone model, the Concept series now covers all major ranges of the saxophone family. Since its introduction in 2013, the Concept series has remained the benchmark in acoustic precision for classical saxophonists. The addition of the Concept baritone mouthpiece to the alto, soprano, and tenor completes the lineup of a series that has consistently earned high praise for its tonal uniformity and ergonomic design. Combining ease of playability, rich tone and consistency across the entire range, the Concept mouthpiece embodies SELMER Paris' quest for acoustic precision, which dates back to 1885. The sleek, modern design with smooth, graceful lines reflects SELMER's ongoing commitment to innovation. ◆Easy to play: Optimized airflow provides smooth response and natural articulation. ◆Rich and uniform tone: Maintains perfect balance across the entire range, producing a wide and expressive sound. ◆Designed to enable acoustic accuracy and stability, as well as precise control of sound quality and pitch. ◆Innovative ergonomic design: Comfort and sophisticated beauty born from flowing, elegant lines.■Opening: 2.03mm...equivalent to Selmer C* and just under 190 (This is just a rough guideline) Facing: 30mm ■Round chamber■Material: Ebonite■Accessories: Outer box, drawstring bag, patch (1 piece) *Ligature and cap sold separately
