This short, simple but elegant jig by Brian Ring comes from Ireland (Lisnagun probably refers to the Iron Age ring fort of Lisnagun in County Cork). As such, it's an ideal tune with which to practice learning by ear! In my video, I've broken the music into short phrases before putting the whole thing together at the end. The sheet music is tucked away at the bottom of the page for those who need a bit of a prompt!
This popular tune is great to improvise around, and features on the amazing album by Tabache, Are You Willing?
