In the 18th century, there was talk of a “chemical harmonica”.
“An instrument with dancing flames, invented by Mr. Kastner; it is a type of organ in which the pipes are replaced by glass tubes, which are used to house flames supplied by two lit gas outlets; when the flames were drawn together to merge, the sound died, and when they were moved apart, the sounds produced become more or less high or low, depending on the length of the tubes” Dict. Littré.
Invention of Mr Georges Frédéric Eugène Kastner (1852- 1882) who wrote a book and lodged a patent for “The singing flames” in 1875.VIDEO: PLAYING ON THE MODEL CONSTRUCTED BY F. KASTNER
