I had been looking for some time for a book dedicated to the 1+ fret. After finding out from Aaron he had written one and Folkcraft had it there was no question what book was to be added to my Dulcimer book library. The information provided and progression of work has given me new understanding of the fret and how it adds to additional chord choices and sounds I’ve been looking for. Beginners to advanced players will benefit from the content here. This book is a keeper!
