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.
EmMaj7 is E, G, B and D# — Em with the major seventh added on top.
It sounds tense and wrong-footed. A minor triad carrying a major seventh: the semitone under the root over a minor chord is the first bar of a line cliché.

Minor tonic — the tonic of the melodic minor.
Also written EmM7, Em(maj7), E-Δ7 or EminMaj7. 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.
EmMaj7 has 7 of them, on the bottom three strings, strings 6-4-3, strings 5-3-2 and the low-middle three, from open position up to the 12th — all in one inversion, so the bass note never moves. The one to learn first is the E shape at the 5th fret, which is the easiest grip here.
Start with 021000 — no barre and 4 open strings. 2 of the 8 shapes here sit in open position. 1 of the 8 needs a barre. Together they cover the neck from the 1st fret to the 14th.
