Recently came across this lost classical instrument, a tonal cross between a flute, a theremin, and the transporter in Star Trek: The Original Series. More commonly known as the Glass (h)armonica, it has been around for hundreds of years and was incorporated by many of the great Classical and Romantic era composers and may have been improved upon by Ben Franklin. Sound is produced in the same way as when one runs a wet finger around the top of a wine glass.
Thoughts?
