Sí Bheag, Sí Mhór (O'Carolan). Irish folk tune. Tin whistle and gitarrenlaute. St Patrick's Day Greetings. Sí Bheag, Sí Mhór, “Small Fairy Mound, Big Fairy Mound“, is an Irish folk tune. The title uses the word 'Sí', the Irish Gaelic for 'fairy mound'. The tune is usually attributed to blind harpist and singer Turlough O'Carolan (1670 – 1738) as his first song. Sí Mhór (Sheemore) and Sí Bheag (Sheebeg) are the names given to two small hills, situated close to each other in south County Leitrim, said to be ancient burial sites, and to a site in Carolan's birth county of Meath.
