Chord Triangulation 2 is the second part of a pair of video mandolin lessons by Bradley Laird, which teach you how to play almost any chord progression without thinking of the chord names at all!
The method taught in this two-part video series is how good mandolin players seem to never miss a chord change in a jam session. Once internalized, this method disposes with a lot of thinking which gets in the way of good music and fun.
The lesson download includes the 24:29 minute video lesson, 9 MP3 audio practice tracks and a PDF file with all of the chord progressions.
