From the manufacturer's catalog: C Trumpet "Metropolitan." This is the latest B&S trumpet model, designed with input from artists active in the New York Philharmonic and the Metropolitan Opera Orchestra. It features the "Harmonic Balancing System," which allows the player to adjust the weight balance and playing feel to their preference by changing the weight of the balancer on each slide (see photos 15 and 16). This high-spec model combines B&S's traditional craftsmanship, such as a hand-hammered, one-piece bell, with the latest technology. The C Trumpet "Metropolitan" was jointly developed by 〈B&S〉 and Josh Landress, an expert in brass instruments based in New York. Incorporating the opinions of artists active in the New York Philharmonic and the Metropolitan Opera Orchestra, the design of the bell, lead pipe, valve block, and more were all reviewed and newly designed. The extremely lightweight piston valves improve operability, and the hand-hammered, one-piece bell employs a side seam, creating an open sound and a moderate resistance. The Harmonic Balancing System※ includes three different types of balancers with varying weights for each slide knob, allowing for adjustments to suit each player's preference. The "Metropolitan" is a new C trumpet that fuses traditional German manufacturing techniques with the latest American design.
