|Irish drum called a Bodrhan|
Irish traditional music includes drinking songs, reels, hornpipes, jigs, walttzes, and many more types of tunes. The tunes are usually binary, i.e. in two parts, each part of which generally repeats. Instruments used to play these tunes included the harp, fiddle, whistle, button accordian, and uilleann pipes ( a type of bag pipe). The "rhythm section" is often the Bodhran, a drum like percussion instrument that is played with a wooden clapper.
Luckily for us, the Irish brought their music with them during the great migration of the Irish to this country, and their music was so powerful that it had a huge influence on our own folk music, particularly in the Appalachians.
There are thousands of examples of Irish music on You Tube. I picked out 3 that I like. If you are interested I suggest that you just poke around in You Tube and discover what you like for yourself. The first, http://www.youtube.com/watch?v=SsEnm5whbT8, is Morrison’s Jig. This version is an electronic one, but I could hear it on acoustic instruments. The next, http://www.youtube.com/watch?v=eANj5UZRfYI, offers a good example of whistle playing, in this instance by Joe McKenna. Finally http://www.youtube.com/watch?v=eANj5UZRfYI offers more than one tune all featuring the fiddle.
