Free and flexible.
Rovner Light ligatures incorporate an old idea for creating natural sound, softly holding the reed to the mouthpiece with no pressure points, just as if the reed were tied on with a string. They fit most hard rubber alto and some tenor and baritone sax mouthpieces.
Rovner Ligatures greatly improve reed playability. Reeds that are totally unplayable on other ligatures will often perform well with the Rovner. The ability of the Rovner Ligature to extend reed life is amazing. While more rigid ligatures actually hammer the cane fibers during vibration, eventually destroying the reed's tonal vibrancy, most players working with Rovner ligatures find their reeds play until the tips finally succumb to fatigue and fall apart.
