Bag Pipes and Uilleann Pipes
Bag Pipes, to start of with, date back to the ancient civilizations, therefore, they come in different shapes and sizes. This type of instrument is most popular throughout Europe and were first made from goat and deer skin along with a reed pipe. This instrument is classified as a wind instrument because it depends on the direction and current of air to produce good sounds. (http://www.music.iastate.edu/antiqua/bagpipe.htm)
On the other hand, Uilleann pipes are most popular in Ireland, specifically to those of a higher class. By the 18th century, these pipe instruments became more popular than the harp (which was declared as the resemblance of Ireland for music). Now, this instrument is used all accross the world for entertainment and military drill purposes.
