As with many other parts of the world, song and dance form the two main categories of the Irish folk music.  The music of IRELAND has strong modal influences and its form is usually quite simple—AABB or AABA would be two examples.  What gives these jigs, hornpipes and reels that light dance-like feeling is that they use meters such as 6/8 and 9/8.  Instruments common to Irish music include the bodhran (a frame drum), fiddles, pipes, whistles, the harp and reed instruments such as the accordion and the mouth organ.
