Fortissimo AN.05 Large Ligature Set Overview
Fortissimo AN.05 is a silver plated large ligature set designed to secure a reed on bass clarinet or hard rubber saxophone mouthpieces using an alternative ring-and-support system rather than a conventional ligature. The ring is engineered to avoid contacting the mouthpiece or reed, aiming to reduce vibration loss and support clearer projection while allowing fast changes in reed support to tailor response and tone.

Who the AN.05 Large Ligature Set Is For
The Fortissimo AN.05 is a large-format ligature set for bass clarinet or hard rubber saxophone mouthpieces that holds the reed with a ring-and-support design instead of a traditional screw ligature. Because the ring does not touch the mouthpiece or the reed, the system is intended to minimize damping and preserve reed vibration, which can help with projection and nuanced control.The AN.05 is suited to players who want fast, repeatable tone and response changes without swapping mouthpieces or reeds. The included supports are designed for distinct tonal profiles: the rubber support with two lengthways lines is intended for a velvety, mellow sound; the metal support with two lengthways lines is intended for a brighter sound and freer expression often favored in modern music and jazz saxophone; and the four-pointed metal support is intended to create a rounder, broader sound by increasing effective chamber space, a profile associated with classical playing and clarinet clarity. This modular approach can also help players manage pitch and response differences between reeds and mouthpieces.
Common Questions About The Fortissimo AN.05
What mouthpieces does the Fortissimo AN.05 Large fit?
It is designed to fit bass clarinet mouthpieces and hard rubber saxophone mouthpieces that require a large ligature size.
How is this different from a conventional ligature?
Instead of a traditional ligature that clamps around the mouthpiece and reed, the AN.05 uses a ring that does not contact the mouthpiece or the reed and interchangeable supports that contact the reed to provide stability while aiming to reduce vibration loss.
What do the different supports change?
The rubber support (two lengthways lines) is intended to produce a more mellow sound, the metal support (two lengthways lines) is intended to be brighter and more direct for modern or jazz styles, and the four-pointed metal support is intended to be rounder and broader, often preferred for classical clarinet applications.
