DAVID SYMINGTON- FLUTE AND PICCOLO STOPPERS AND CROWNS
L To R : Piccolo Stopper Copper Crown Flute Stopper
Beryllium is a new comer to the list of metals that I have tried over the years. Its density at 1.85gm. per c.c. is very low and and a flute stopper weighs only 3.6gm. as against tantalum at 27gm.. On my flute the sounds is very vibrant and I can feel the vibrancy in my fingers; it is remarkable! I use a copper crown with it.
