We will be using the Fiddle & Song book this Summer for our studio repertoire. You can order the book (below). It is a great resource for both beginning through intermediate fiddlers. I love that the book is available for violin, cello, piano and viola. It also includes the guitar chords and lyrics with a great authentic sounding play/listen along recording.
The book has simple arrangements with harmonies included, teaches the basic backup techniques required to create an ensemble and also has designated teacher or advanced students parts written at a simple middle school level.
The book closely mirrors the Suzuki or American Fiddle Method learning fundamentals but is more fun for the students to play along with because listening tracks, slow down practice software and play-along karaoke like backup tracks are included. Many of the songs have lyrics you can sing along with or you can just play the tune twice as long.
The repertoire includes standard old-time fiddle, Celtic medleys, Appalachian modal tunes and a fun catchy blues tune.
