There are basically 3 types of bagpipe music: The Marches, The Dancing Tunes and the Classical Music or "Old Music" called the Piobaireachd. The Kilberry Book is a repertoire book consisting of 120 tunes. This is a great book to have in your collection. When I bought mine in the 70's I paid $16.50 for it. Today it sells for $68.00. Hey if you buy one and don't play the tunes, it will be a bagpipe asset that will increase in value over a period of time!
