Feis Ceoil (English: Festival of Music) is an Irish music society which has an annual cultural festival of music and dance. It was first organised in Dublin in 1897 by Dr. Annie Patterson and Edward Martyn for the purpose of stimulating musical studies in Ireland and encouraging native performers and composers. It is a result of the general Gaelicising programme of the Gaelic League. It consisted of competitions for performance and composition and was supported by all musicians of the day, both national and classical. Prizes aggregating £800 were distributed among the successful competitors.
Since those early years, the Feis Ceoil has undergone many changes to accommodate the development of music in Ireland. It has expanded to more than 170 competitions in all instruments, including voice, and covering all ages from 8 years upwards. Famous competitors over the festival's history include tenor John McCormack, author James Joyce (as a singer), Irish Tenor Finbar Wright, broadcaster Seán Óg Ó Ceallacháin and violinist Cora Venus Lunny.
In 2006 the Royal Irish Academy of Music Percussion Ensemble were awarded first prize in the Chamber Music Competition, becoming the first percussion ensemble in the Feis's history to enter and win.
