Rovner Ligatures also 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 unparalleled. More rigid ligatures actually hammer the cane fibers during vibration, eventually destroying the reed's tonal vibrancy. Not so with Rovner; most players find their reeds will play until the tips finally succumb to fatigue and fall apart! Due to the design of the Rovner ligatures, they fit a wide range of mouthpieces. The above descriptions are general but are accurate for MOST mouthpieces.
