An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.
Emaj13 is E, G#, B, D#, F# and C# — Emaj9 with the thirteenth on top, and the eleventh left out.
It sounds full and wide open. Six notes into four fingers means something goes: keep the third, the seventh and the thirteenth.

Tonic — the major sound with most of the scale showing.
Also written EM13, EΔ13 or E major 13. The same chord either way; which spelling you meet depends on who wrote the chart.
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
Emaj13 has 4 of them, on strings 6-5-4-3-2, strings 6-5-4-3-2-1, strings 6-4-3-2-1 and strings 5-4-3-2-1, from the 4th fret up to the 6th — every inversion the chord has: E in the bass and D# in the bass. The one to learn first is the E shape at the 4th fret, which is the easiest grip here.
Start with x76644 — no barre and low, at the 4th fret. 1 of the 7 shapes here sits in open position. 5 of the 7 need a barre. Together they cover the neck from the 1st fret to the 14th.

Tensions. A shell of Emaj13, root, third and seventh, leaves a string free, and the tones that belong over it are the #11 (A#).
How you get to it. The turn that lands on Emaj13 is F#m7 to B7 — the ii and the V of E — and B7 shares its third and seventh with F#m7, so the hand barely moves between them.
In which keys. Every note of Emaj13 belongs to C# minor (the ♭III), E major (the I, the tonic), Ab minor (the ♭VI) and B major (the IV, the subdominant).
Every note of Emaj13 is in E major and E lydian.
Change one note of Emaj13 and you have Emaj9 (drop the sixth), Emaj11 (the sixth becomes a fourth), E69 (drop the major seventh) or E13 (the major seventh becomes a flat seventh).
Emaj13 is a major chord — root, major third, fifth. Major chords on every root.
On Emaj13’s sound and use this page follows Ted Pease & Ken Pullig, Modern Jazz Voicings (Berklee Press, 2001). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
