Jer Mac's

Polka · 2/4 · D major

Jer Mac's is a traditional Irish polka in two-four meter and the key of D major, though its specific geographic origin and exact composer remain unknown. The tune features the brisk, lively rhythm and bright character typical of Sliabh Luachra dance music, designed to accompany energetic set dancing. Because of its obscure historical background, players focus on its rhythmic drive and traditional ornamentation rather than any specific programmatic association.
