Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top.
Eb6 is Eb, G, Bb and C — Eb with a major sixth added on top.
It sounds warm, and finished without being sweet. It closes a tune as firmly as the triad does but without the maj7’s shine, which is why so many standards end on one.

Tonic — an ending chord.
Also written Ebmaj6, EbM6 or Eb major 6. The same chord either way; which spelling you meet depends on who wrote the chart.
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
Eb6 has 5 of them, on the low-middle three, the bottom three strings, strings 5-3-2 and strings 6-4-3, from open position up to the 10th — all in one inversion, so the bass note never moves. The one to learn first is the Eb shape at the 5th fret, which is the easiest grip here.
Start with xx1313 — no barre and down at the nut. None of the shapes for Eb6 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 4 of the 9 need a barre. Together they cover the neck from the 1st fret to the 13th.

Tensions. A shell of Eb6, root, third and seventh, leaves a string free, and the tones that belong over it are the 9 (F) and the #11 (A).
How you get to it. The turn that lands on Eb6 is Fm7 to Bb7 — the ii and the V of Eb — and Bb7 shares its third and seventh with Fm7, so the hand barely moves between them.
In which keys. Every note of Eb6 belongs to C minor (the ♭III), Eb major (the I), F minor (the ♭VII), G minor (the ♭VI), Ab major (the V) and Bb major (the IV).
Every note of Eb6 is in Eb major pentatonic, Eb major, Eb lydian, Eb mixolydian and Eb lydian dominant.
Change one note of Eb6 and you have Eb (drop the sixth), Ebmaj7 (the sixth becomes a major seventh), Ebm6 (the major third becomes a minor third), Ebadd9 (the sixth becomes a ninth), Eb69 (add the ninth) or Eb7 (the sixth becomes a flat seventh).
Eb6 is a major chord — root, major third, fifth. Major chords on every root.
On Eb6’s sound and use this page follows Mark Levine, The Jazz Piano Book (Sher Music, 1989). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
