Asymmetrical tone holes


Vortex, air pressure, flow rate... These physical characteristics directly impact each other in any tone hole. The ideal shape of a tone hole significantly enhances intonation, sound and playing feel. An asymmetrical tone hole optimizes the air flow, reduces various air pressure zones and promotes a homogeneous, stable and free air flow. Differences in intonation and tone between forte and piano can be balanced much more easily with this asymmetrical tone hole.
