Many children are drawn to the trombone for its powerful sound and fun sliding motion, but most trombones are too large for small arms to handle. The Yamaha YSL-350C solves this problem with a compact design that maintains standard slide positions while eliminating the need for the longest extensions through its ascending Bb/C rotor.
This innovation allows young or beginner players to perform a full scale comfortably without struggling to reach extended positions. Built with Yamaha’s renowned craftsmanship, it features a chrome-plated nickel-silver inner slide for smooth response, a yellow brass bell for rich resonance, and durable braces for stability. With its precision engineering and lightweight, balanced design, the YSL-350C is the perfect starting instrument for aspiring trombonists.
