Glass harmonica consists of up to 52 chromatically tuned resonating metal rods that are set into motion by attached glass rods that are rubbed with wet fingers. The Cristal di Baschet differs mainly from the other glass instruments in that the identical length and thickness glass rods are set horizontally, and attach to the tuned metal stems that have added metal blocks for increasing resonance. The result is a fully acoustic instrument, and impressive amplification obtained using fiberglass or metal cones fixed on wood and by a tall cut-out multi-resonant metal part in the shape of a flame.
