Watch the Diatonic Triads in C online guitar lesson by Brad Carlton from Guitar Lab: Solid Strumming
This lesson presents the diatonic triads in the key of C. They are as follows: C the I chord, Dm the ii chord, Em the iii chord, F the IV chord, G the V chord, and Am the vi chord. We will not be dealing with the chord built off the seventh step of the major scale.
You will receive a fingerboard diagram chart displaying all six of these diatonic triads as well as the C major scale in first position. You will also receive an alternate chord for the iii chord. This chord will be the I chord over the III bass note.
