In Ireland and other countries, a folk music revival has been gong on since the beginning of the 20th century. Many musicians have sought to draw on the original sources of folklore traditions as a way of renewing their own art, but this “renewal” is not always geared to preserving traditional culture before its disappearance.
Here is an interesting documentary on how the revitalization of Irish folk music in the 1960’s came about: http://youtu.be/39D0J8SzQMA
In central Europe, Endre Abkarovits (citation below) wrote a very interesting paper in which he compares both the Irish and Hungarian folk music revival; both countries have covered similar paths in pursuit of “preserving” their musical culture in the latter part of the 20th century.
A video of Hungarian folk dances, shows a musician on stage walking around with a set of elbow pipes, reminiscent of the Irish “píobaí uilleann” (see 05:10 mark). http://youtu.be/BXGovKBEaHo
