Watch the Open Gm Tuning online guitar lesson by Sonny Landreth from Slide Supernatural
Open G minor is the same as open G but we lower the B string to Bb to give us the minor third. So from low to high D, G, D, G Bb, D. As with all the tunings we have covered take time to investigate the octaves available. For me this is a real vibey sound and is great to add mood to a piece or a track when you want to do layering, melody or soloing, harmony, rhythm, anything really it really works well. And like D tuning and the lower tunings - I like having that depth on the low end and still have harmonics ring out on the top strings. And even just fretting those, letting that all ring out. No matter what you do, that minor third is so prevalent and affects the overall sound, it gives it that atmosphere.
