As soon as Benjamin Franklin completed his glass harmonica in 1761, he went on tour demonstrating the instrument all over Europe. Mozart was eventually requested to compose for it in 1791, hence launching an endless series of composers writing for the latest technological achievements of the day – the mid-18th c. automatons and mechanical instruments music being the actual birth of industrial music as we know it. The scientist and magnetism specialist Anton Mesmer (1734-1815) even used the glass harp to put his subjects into hypnotic trance. But composers loved it.
