Can you discuss the origin of Harmonium ?
The first harmonium was invented by Christian Gottlieb Kratzenstein (1723-1795) who was the professor of physiology at Copenhagen. The design of the harmonium was altered by Gabriel Joseph Grenie between the years 1756-1837, and he called it an ‘orgue express’, since it produced diminuendo and crescendo sounds. Grenie’s instrument was then modified by Alexandre Debain who improvised it further and named it ‘Harmonium’ which he then patented in 1840. However, other alterations and improvisations shaped the harmonium further as the firm of Mason & Hamlin from Boston introduced suction bellows in it during 1860, which became popular in America.
