High Quality Content by WIKIPEDIA articles! Sean-nós is a highly ornamented style of unaccompanied traditional Irish singing. It is one of various sean-nós activities, which also include sean-nós dancing. These forms of Irish dance and song have been documented by ethnomusicologists. The tradition of sean-nós song was exclusively oral, and remains customarily so. However a few songs were known to have been conveyed to script as early as the 16th century. A songbook for Elizabeth I contained English interpretations of sean-nós songs. Songs started to be more extensively written down in the eighteenth century; and distributed in print from then on. New composition is a controversial issue within sean-nós song circles. Some singers insist that the traditional should be supplemented with new material, arguing that since society has changed, then the content of the lyrics should reflect this also. On the other hand, some singers say that only the older, "traditional" songs represent the essence of sean-nós song and that therefore deserves a protected, preferential status.
