Accordion – Bosca Ceoil
The Accordion is a bellows operated, free reed, diatonic instrument on which the melody notes are articulated by buttons or keys operated by the right hand, bass notes by those on the left. Each button is designed to activate from 2 to 4 reeds. The accordion spread to Ireland late in the 19th century. Modern Irish accordion players generally prefer the 2 row button accordion. Unlike similar accordions used in other European and American music traditions, the rows are tuned a semi-tone apart. This allows the instrument to be played chromatically in melody.
