VIVO: The famed Hungarian flutist Janos Balint, was very influential in developing this headjoint.
It has a powerful and responsive character, using its exclusive cambered taper.
This VIVO design uses a considerable amount of modern sculpturing design to produce a radiant sound.

FORZA: This model is similar to the VIVO Model with a traditional taper.
It is a very responsive headjoint,
designed for all around performance.

CLASSICO: This is a more traditional Headjoint, and had a warm and rich projection.
The French influence is obvious here. An elegant and refined tone is achieved by moderate over and
undercutting upon this classical oval embouchure hole.

BOLERO: This mode is similar to the CLASSICO, but with slightly more undercutting to decrease
the resistance.
The French sound is retained in this easy blowing version.

BRIO: A truly glorious core, with a solid low register. It is characterized by considerable under and over cutting,
with a tall riser.

I've only heard of the Forza..
