I have found the book by "Aaron O'Rourke-1 1/2 Fret: Using It And Getting The Most Out Of It" easy to learn from and it's fun to learn the difference in the sound the 1 1/2 fret contributes to the songs when used. I am having fun trying this new fret on my new Folkcraft Dulcimer and applying it to other songs I to find when and where it can be used.
New Sounds abound!!
