As guitar players, we inherit EADGBE, DADGAD and drop C. We copy what we see. I talk about the case for and against making making your own tuning, writing a song in a tuning that exists for that song, and my thoughts.
I talk about the beautiful open D tuning, including how to tune to DADF#AD, easy 1-finger chords, slide-friendly shapes, and how its different from DADGAD.
