Celtic styles of music exist was made during the nineteenth century, and was associated with the revival of folk traditions and pan-Celtic ideology. The Welsh anthem "Hen Wlad Fy Nhadau" was adopted as a pan-Celtic anthem. Though there are links between Scots Gaelic and Irish Gaelic folk musics, very different musical traditions existed in Wales and Brittany. Nevertheless, Gaelic styles were adopted as typically Celtic even by Breton revivalists such as Paul Ladmirault. Celticism came to be associated with the bagpipe and the harp. The harp is considered to be the national instrument of Wales and is used to accompany penillion singing (or cerdd dant) where the harpist plays a melody and the singer sings in counterpoint to it. The roots revival, applied to Celtic music, has brought much inter-Celtic cross-fertilisation, as, for instance, the revival by Welsh musicians of the use of the mediaeval Welsh bagpipe under the influence of the Breton binioù, Irish uillean pipes and famous Scottish pipes, or the Scots have revived the bodhran from Irish influence. Charles le Goffic introduced the Scottish Highland pipes to Brittany. Unaccompanied or A cappella styles of singing are performed across the modern Celtic world due to the folk music revival, popularity of Celtic choirs, world music, scat singing and hip hop rapping in Celtic languages. Traditional rhythmic styles used to accompany dancing and now performed are Puirt a beul from Scotland, Ireland, and Cape Breton Island, Nova Scotia, Sean-nós singing from Ireland and Kan ha diskan from Brittany. Other traditional unaccompanied styles sung currently are Waulking song and Psalm singing or Lining out both from Scotland. The emergence of folk-rock led to the creation of a popular music genre labelled Celtic music which "frequently involves the blending of traditional and modern forms, e.g. the Celtic-punk of The Pogues, the ambient music of Enya ... the Celtic-rock of Runrig, Rawlins Cross and Horslips." Pan-Celtic music festivals were established, notably the Festival Interceltique de Lorient founded in 1971, which has occurred annually since. Festivals The Scottish Mod and Irish Fleadh Cheoil (and Gaelic Céilidh) are seen as an equivalent to the Breton Fest Noz, Cornish Troyl and Welsh Eisteddfod. The Celtic Media Festival is an annual 3-day event that promotes the languages and cultures of the Celtic Nations and Regions in media. This festival takes place in a different Celtic nation every year and has been running since 1980. The birthdays
