The Music Division’s bonnie collections offer a variety of ways to celebrate this St. Patrick’s Day. Play an Irish bagpipe from the Dayton C. Miller Flute Collection. Follow along to the reels described in Rinnce na h-Éireann : a simplified work on the performance of the dances of Ireland, from An American Ballroom Companion: Dance Instruction Manuals. Develop your jig with sundry offerings from the Historic American Sheet Music Collection, 1850-1920 in the Performing Arts Encyclopedia, where you can pine for The Colleen you left in Killarney; take pride in your heritage with George M. Cohan’s The Irish American; and of course send the little ones to sandman with Too-ra-loo-ra-loo-ra, that’s an Irish lullaby.
