Mandolin Primer Part 2 The Mandolin Primer Part 2 by Bert Casey is a Multi-Touch eBook with Audio & Video. This is a continuation of Mandolin Primer Deluxe Edition and contains 7 additional bluegrass standards. This eBook contains over 30 minutes of HD video instruction using close-ups and split screens to make the movements of each hand perfectly clear. In addition, the large on-screen tablature has a moving pointer that indicates each note as it's being played. Once you have memorized a song and can play along with the video, you can start practicing with the Audio Tracks. This is a unique practice tool that plays full length versions of all the songs at five speeds along with an acoustic band. This is the missing link between playing the mandolin and jamming with others.
