Who the AN.03 Ligature Set Is For
The Fortissimo AN.03 is a small-format ligature set for clarinet and saxophone mouthpieces that secures the reed using a ring and removable support rather than a traditional clamp-style ligature.
This design is intended for players who want a fast way to adjust response and tonal color while keeping the reed supported without forcing it. Because the ring touches neither the mouthpiece nor the reed, the system is designed to reduce vibration loss and help with projection, while also supporting detailed control for effects such as slap, subtone, and flat. The included supports provide clearly different tonal options: the rubber support (two lengthways lines) for a velvety, mellow sound; the metal support (two lengthways lines) for a brighter, freer feel suited to modern styles and jazz saxophone; and the four-pointed metal support for a rounder, broader sound associated with an increased chamber effect, often preferred for classical playing and clarinet.
Common Questions About the Fortissimo AN.03
Will the Fortissimo AN.03 fit my mouthpiece?
The AN.03 Small Ligature Set is intended to fit clarinet, alto sax, and metal saxophone mouthpieces. If you are unsure about sizing for a specific mouthpiece model, contact us with the mouthpiece make and model for confirmation.
What is the benefit of the interchangeable supports?
The supports let you change how the reed is supported against the mouthpiece, which can noticeably change response and tone. Rubber tends toward a mellow, velvety sound; the lined metal support tends toward a brighter sound; and the four-pointed metal support tends toward a rounder, broader sound often favored for classical clarinet.
Does the ring touch the reed or mouthpiece?
No. In this system, the ring is designed to touch neither the reed nor the mouthpiece, which is intended to reduce vibration loss compared with conventional ligature contact points.
