Heligonka
Eastern European diatonic button accordion
From Wikipedia, the free encyclopedia
The heligonka or helikónka (in Slovak: heligónka) is a Czech, Slovak and a Polish Goral[1] diatonic button accordion,[2] similar to the Alpine Steirische Harmonika. Like the latter, the heligonka differs from other types of diatonic button accordions by having a supplemented and amplified bass part.
