Uncork your flute with Rhino Resonator! Unlike cork, which dampens the vibration of your headjoint, the Rhino Resonator works as a linked resonator. Not only is there minimal contact with the wall of the headjoint by the silicon O-ring (while providing a complete, air-tight seal), the Rhino Resonator actually works with the vibration of the headjoint to enhance resonance and projection.
No more fumbling between books and pages causing aggravation and wasted practice time! This flute fingering calculator is convenient, easy to use, made from a durable plastic, and versatile. A great resource for all students and teachers!
