- Brass Instrument Mute Structure for Sound Reduction and Blowing Feel
Porous sound-absorbing layers and buffer members cut brass instrument volume while preserving blowing feel and controllability.
- Equilibrium Piston Valve Geometry for Low-Resistance Brass Airflow
Curved piston passages extend brass instrument tubing for lower pitch while keeping airflow resistance consistent across valve positions.

A flexible leadpipe-mounted thumb guide uses friction fit and a recessed thumb rest to stabilize hand position, improve comfort, and support tone control.
