Watch the Open G Tuning online guitar lesson by Sonny Landreth from Slide Supernatural

Let's start off by taking a look at open G tuning. We have to retune some strings to get there but it's easy, from low to high we have D, G, D, G, B, D.  This makes sense, of course, because a G chord is spelled G, B, D. Each tuning gives us some very cool and unique options to work with, and what I love about open G tuning are the octaves contained within it. We have three D's on the 6th, 4th, and 1st strings, and two G's on the 5th and 3rd strings. When played in unison it gives us a great sound that I use quite a bit. These octaves work great with fretted notes or using the slide. We hear this sound in classic Delta and Country blues tunes all the time. I also like to take advantage of the top string for some more lyrical and melodic lines that I can play against the open lower strings.
