Gibson has been posting free instructional videos on their web site of late. Most of them have reflected the larger size of their market that comes from the world of rock music, but two mandolin lessons were posted recently.
They are taken from How To Play Mandolin by Bert Casey, and show both a split-screen video and on-screen tab for the tune Blackberry Blossom.
Find the mandolin videos – and all the other free lessons – at Gibson.com.
