Features: The intonation tone is very good, with very strong penetration and expressiveness, suitable for: grade examination / professional performance

Special copper material for musical instruments: thickened brass specially used for wind music is selected, the ratio of copper, zinc, tin and nickel is very stable, the vibration is more uniform, the fine inner tube is drawn, the sealing performance is good, and the wear resistance is good.

Excellent hand-made craftsmanship in modern factories, strong timbre, deep and powerful sound, and rich expressiveness. CNC computer-controlled production, the overall mold opening is accurate, well-made, accurate in size, adhering to hand-grinding and drawing the tube, high air tightness, and each pitch error can be controlled within 20 cents. According to aerodynamics, the airflow, resistance, air force, and pressure are calculated, and the fine numerical control design is adopted, which is fine to every arc to reduce air resistance. After mastering the skills, even small children can easily blow.
