Big Dan O'Mahony

Hornpipe · 4/4 · A mixolydian

Big Dan O'Mahony is a traditional Irish hornpipe whose exact composer and historical origins are not definitively established. Written in 4/4 meter and typically played in the key of A mixolydian, it features the bouncy, dotted rhythms characteristic of standard Irish dance music. Because detailed historical associations for the tune are lacking in reliable records, players generally focus on its lively tempo and structured phrasing to drive traditional set dances.
