Anyone who is serious about learning Irish traditional music will eventually come across O'Neill's Music of Ireland, a collection of well over 1000 tunes. This book contains a selection of one hundred tunes from this collection, arranged into sets for mandolin which can be used at sessions, and for dancing. The book includes hints, tips and comments for playing the tunes and some of the tunes also have alternative melodies and harmonies for added variety and interest. At the back of the book, there are guitar chords with standard and open D tuning, and a mandolin fretboard chart that you might find useful.
