Here are all of the 3-string Major Triads in the Key of C.
In every Major scale, there are three Major chords:
the I chord, the IV chord, and the V chord.
They are expressed using upper-case Roman numerals.
They are arranged here in such a way as to facilitate memorization.
I’ve taken great care to notate my preferred fingerings but do keep in mind that they are always negotiable depending on the music at hand.
