This chord is moveable and has its root note on the B string (indicated by the black box in the chord diagram). This chord is fingered by playing the root note on the B string with your middle finger, your first finger on the A string, your 3rd finger on the D string and little finger on the G string.
13th chords can be played in place of most 7th chords. It can replace chord V in major keys.
Officially 13th chords use these degrees of the major scale: 1, 3, 5, b7, 9, 11, 13 though in practice (especially on guitar as there more notes than strings!) some notes are left out. The most important notes are the 3rd, b7, 13th, 9th, root, 5th and lastly the 11th in roughly that order.
E13th uses the notes: E, G#, B, D, F#, A, C#
Our inversion uses the notes in this order: D, G#, C#, E
