The first two pages of the 6-page micro course that shows how every guitar chord is built from the same simple idea.
Inside the free PDF: the major scale and its numbers, tones and semitones in frets, how 1, 3 and 5 make a major chord, and how changing one note gives you minor, diminished and augmented chords, with chord boxes. Sevenths, 9ths, sus chords, 11ths and 13ths stay in the full course.
