The tune settings in this book are all 'session friendly', i.e. you can learn them exactly as written and know that you will have a perfectly acceptable version. However, I consider it unwise to learn a tune from only one source and I would suggest strongly that, when learning a new tune, you pay heed to other books, recordings and live performances. It is important to note that the settings in this book are greatly influenced by the instrument I play, the D/G melodeon (an accordion system rarely found in Irish music circles - B/C and C sharp/D are the norm). I've made a conscious effort to allow this to happen in order to give the book its own unique character. When choosing books, take care not to be put off by the title; some of the best sources of tunes are from tuition books. Just because the book cover says 'Learn to Play the Banjo', don't think it's of no use if you play the tin whistle.
