The classification of the shapes of the 15 basic chord types with roots on 6th and 5th strings. R, Rm, Rmaj7, R7, Rm7, Rm7b5, R7b5, R6, Rm6, Rdim, Rdim7, Raug, Raug7 (or Rm7#5), Rminmaj7 R7#5
We must remark here the identities for lower relative chords,which render 6th chords to 7th chords of the diatonic scale , C6=Am7, (Am is lower relative to C) and Dm6=Bm7b5 (B is relative to Dm, and Bm7b5 is the 4-note chord with 7th of the diatonic scale at the 7th step vii of the scale). If we move by an interval of 3rd lower to the root (inside the scale) of a 3-note chord of the scale, we get a 4-note chord with 6th, which extends the initial 3-notes chord by its lower relative, and we get sounds as in Romani (Gypsy) Jazz.
Before this post the reader must study the posts 40 (that classifies intervals), the classification of 2-string triads , and 38 (that classifies 3-string triads) and 35.
Although very often these chords are referred as Jazz chords, the truth is that these chords appear long time before Jazz was developed , for example as 4-notes chords of the diatonic, Harmonic minor, Harmonic double minor, Melodic minor, melodic double minor and other oriental scales as in the post 52.
Jazz is utilizing partial chords. In other words, chord-shapes where not all of the 6 strings participate. Usually 2 strings are muted. We will see that all the 14 chords above with roots on the 6th or 5th string are partial shapes of the DAE system.
The shapes of these chords with roots on the strings 4th, 3rd,. 2nd 1st will be covered as Ukulele or Bouzouki chords in the post 16 where the 4 higher strings of the guitar are treated as a separate ...instrument!
We will present also the shapes of these chords for a guitar tuned in all strings by intervals of pure 4ths (5 semitones).

Here we see 3 ways to play a diminished chord. The root note name does not matter , what we want to show here is only the shape. R stands for root. In the first shape the root is the D note.
