NOTE: The Chord Charts are now vastly improved by the use of a new software package called Guitarator Toolbox. The chart details are much improved and they are provided in acrobat file format so you can print the diagrams. You will need to have the Acrobat file reader (free) installed on your computer to view these diagrams however.

I've highlighted with "**" the standard chord forms used most often in chord progressions. You may want to start with these if you're trying to build off a progression you're already familiar with. A blues progression would generally use the I7, IV7, V7 chords so these provided as well. This certainly isn't an exhaustive list, but probably more than you'll find in most books on Open Tunings.
