Accordion Performance by Vincenzo Sicurella: Light My Fire @ Ithaca College The accordion in its contemporary form was first created in Europe in the early 1800s, and its basic form is believed been invented in Berlin in 1822 by Christian Friedrich Ludwig Buschmann. An instrument called “accordion” was first patented by Cyril Demian in 1829 in Austria. The accordion is classified as a “free reed instrument.” Accordion is a box-shaped musical instruments of the bellows-driven free-reed aerophone type, colloquially referred to as a squeezebox. These first accordions were bisonoric diatonic button accordions, which means they had buttons instead of piano keys, and each button sounded different pitches depending whether when air was pushed in or pulled out using the bellows. Accordion has traditionally used to perform folk or ethnic music, popular music, and transcriptions from the operatic and light-classical music repertoire.
