Cyrill Demian
From a Viennese workshop to a new chapter in the accordion’s history
Cyrill Demian was an instrument maker of Armenian origin working in Vienna. With his sons Karl and Guido, he built organs and pianos. His name is particularly associated with the instrument patented as the “accordion” in 1829.
Their small instrument used bellows and a few keys that sounded chords, a feature reflected in its name. It differed considerably from the large keyboard accordions developed later, but marked an important stage in the history of free-reed instruments.
The invention offered a portable means of producing rich musical accompaniment. Later makers developed its construction, and various forms of accordion spread through folk and concert traditions in many countries. Demian’s legacy lies in this meeting of skilled craftsmanship and musical innovation.
