7th Chords Based on E, A, and D Shapes
In our maps below, we use the E, A, and D chord forms to build the qualities of Major 7, minor 7, minor 7 flat 5, & fully diminished 7. The qualities are in the box on the left and some common symbols for each are below the box. Vertical block lines between fret dots are bars. Most of these chords need to be fretted as shown, but if you figure out a different or better way to finger any of them, go for it!
These are often considered jazz chords, but we can use them in any style where they fit, or in the songs we write.
Every tone is every chord component in fully diminished
Practice fretting each of these voicings. Once you have working fingerings, practice progressions. In Jazz, the most common chord progression [stream of sequentially changing chords is 2-5-1 (ii-V-I)]. As 7th type chords, the qualities in a Major key will be iimin7-V7-IMaj7.
