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.
EmMaj9 is E, G, B, D# and F# — EmMaj7 with the ninth added on top.
It sounds the same unease with more colour over it. The ninth softens the edge without resolving anything.

Minor tonic — melodic minor, extended.
Also written EmM9, Em(maj9) or E-Δ9. 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.
EmMaj9 has 6 of them, on strings 6-5-4-3-2-1, strings 6-5-4-3-2, strings 5-4-3-2-1 and strings 6-4-3-2-1, from the 3rd fret up to the 4th — 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 3rd fret, which is the easiest grip here.
Start with 021002 — no barre and 3 open strings. 2 of the 9 shapes here sit in open position. 4 of the 9 need a barre. Together they cover the neck from the 1st fret to the 14th.

On EmMaj9’s sound and use this page follows Mark Levine, The Jazz Theory Book (Sher Music, 1995). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
