This is a one minute sample of the song "Adagio and Rondo in C minor" by Wolfgand Amadeus Mozart from the CD Music for Glass Harmonica. Mozart was a good friend of Mesmer. Anton Mesmer used the glass harp to put his subjects into hypnotic trance. Mozart wrote this piece for Mesmer. Notice the characteristic "ring" of rim-rubbed glasses. The best of the trance music, the ethereal voices of fine crystal glass. Mesmer's great critic, Benjamin Franklin, invented a glass harp that could be played from a keyboard.
