M. Kastner has manufactured a new musical instrument of a incredibly peculiar timbre, carefully resembling that of the human voice. The ‘pyrophone’ has 3 important boards each individual essential is in conversation with the conduit pipes of the flames in the glass tubes. By pressing on the keys, the flames individual and sound is manufactured. When the tension is taken off, it is right away stilled by the junction of the flames.”
