I created this chord library to be a quick reference guide for some common chords and the easiest way to play them. Most are in the open shape with a few barre chords there also, but I find these all to be the easiest way that also gives a full sound! There is also the intervals that chord uses if you wanted to play the same chord somewhere else on the neck!
Major Chords // Intervals R - 3 - 5
Minor Chords (m or -) // Intervals R - b3 - 5
Major 7th Chords (∆ or maj7) // Intervals R - 3 - 5 - 7
Minor 7th Chords (m7 or -7) // Intervals R - b3 - 5 - b7
Dominant 7th Chords (7 or dom7) // Intervals R - 3 - 5 - b7
