Watch the Open D online guitar lesson by Rich Maloof from 50 Acoustic Guitar Licks You MUST Know
Open tunings aren't everybody's bag, but we're going to include a handful of examples here to remove the mystery. Tune to an open D (low to high: D A D F# A D). Now when you strum all six, you've got a big bad major chord --- D major, naturally enough. You can barre straight across and move majors around the neck with ease, and your harmonics will always repeat a major-chord tonaligies as well.
