Steve Ducke recently contacted me to tell me of his new instructional book (and audio) for Irish tin whistle. It is entitled "A Complete Guide to Playing Irish Traditional Music on the Whistle".
This tutor book, with its accompanying audio files, is intended to give a complete introduction to playing Irish music in the traditional style on the tin whistle; it covers all from the very first notes on the instruments to the most advances ornamentation. The book is broadly divided into two parts, with the shorter first part covering the basics of the whistle (pages 1-48) while the longer second part (pages 49-286) covers the playing of Irish traditional music on the instrument
It is currently available as a download containing 1 print-friendly indexed pdf file (286 pages) and 429 audio files.
