This is so much fun! I perform it in a very subtle way - when behind the bar and off to the side as
if I'm practicing. I only use three glasses and convince the casual onlooker that by cupping my
hands and only going part way around the glass, the tone changes. The volume is loud enough and
"connected" to the glass - it sounds perfect. The price for this is too low compared to the impact
it has on the audience. Making the Wonder Orchestra as a glass harp effect is perfect. It is a
combination of a science effect, magic effect, and a musical effect. Great job!!!
