Basic Backup

This book by Aaron O'Rourke provides Mountain Dulcimer accompaniment ideas for improving any jam, ensemble or duet.  In this book, Aaron breaks down information into chapters, so it's easy to tackle one new thing at a time.  You're then given a few lines of a song to put the new technique into practice.  This book is all about playing complimentary music in a group setting, so everyone sounds even better!
