Permits the reed to vibrate more freely than with conventional metal ligatures. Improves tone, response and intonation of woodwind instruments. Allows reed to swell and shrink without distorting the reed body, reducing the likelihood of leakage at the facing. Reduces peculiar modes of vibration that give rise to uneven scales, poor intonation, squeaks and raspiness. If properly used, will provide greater playing ease, considerably extended reed life and fewer rejected reeds. Is made of the finest materials obtainable. Has a body made of neoprene-impregnated polyester fabric that will not stretch or rot and is chemically impervious; is fitted with corrosion-resistant metal fittings. Undergoes constant scrutiny for possible improvements. All current ligatures feature double-textured ligature body with new T-process Polymer Impregnation.
