of six octaves, and its tone was similar to that of the harmonium. After its invention around 1800, several modifications were made, including the aeolsklavier, aeolomelodicon or choraleon, and aeolopantalon, but all versions had largely disappeared by mid-century.

History

There is some controversy as to its original inventor; most authorities attribute it to Jean Tobié Eschenbach of Hamburg, who is said to have first made it in 1800. Various improvements were subsequently made by other musicians, among whom may be named Schmidt of

Aeolsklavier

A modification of the aeolodion was the aeolsklavier, invented about 1825 by Karl Friedrich Emanuel Schortmann of Buttelstädt, in which the reeds or springs that produced the sound were made of very thin wood instead of metal. For this reason, the quality of tone was made softer and sweeter. It was equipped with a keyboard and with a pedal which triggered a set of

, about the year 1825, from the design of Professor J. F. Hoffmann in that city. It differed from the æolodion in the fact that brass tubes were affixed to the reeds, much as in the reed-stops of an organ. The instrument was of great power, and was probably intended as a substitute for the organ in small churches, especially in the accompaniment of chorals, whence its second name choraleon. It has taken no permanent place in musical history.
