Em7b5 Chord on Guitar
Em7b5 = E – G – A# – D (Root, Minor 3rd, Tritone, Minor 7th)
Em7b5, also called E half-diminished, flattens the fifth of the plain open Em7 shape, and because the whole thing stays in open position, it's a considerably more approachable way to reach this chord quality than the barred D#m7b5 version at the eleventh fret.
E, G, A#, and D make up the chord — root, minor third, diminished fifth, flat seventh. As iiø7 of D minor it's the essential first chord in the minor-key ii–V–i turnaround (Em7b5–A7–Dm), one of the most foundational progressions in jazz-minor harmony, transposable to any key but landing here in one of the guitar's more accessible open-position forms.

Open Position
How to Practice It
Two extra fingers are needed on the A and D strings, both reachable comfortably without a barre, unlike the wider stretch this chord demands up at D#m7b5's cramped eleventh-fret position. Because the flattened fifth is what gives this chord its distinctive half-diminished color, listen closely for that specific note ringing clearly against the rest of the shape, since it's the one interval separating this chord from a plain minor seventh.
Common Progressions
- Em7b5 – A7 – Dm (iiø7 – V7 – i, the classic minor-key turnaround)
- Em7b5 – A7 (iiø7 – V7)
- Gm7 – Em7b5 – A7 (a longer chain resolving to V7)
- Dm – Em7b5 – A7 – Dm (i – iiø7 – V7 – i)
FAQ
- Why is Em7b5 called half-diminished?
- It shares the diminished triad's flattened fifth but keeps a regular flat seventh rather than a fully diminished one, sitting harmonically halfway between a plain minor seventh and a true diminished-seventh chord — hence the name.
- What's the classic progression Em7b5 belongs to?
- The minor-key ii–V–i turnaround: Em7b5 (iiø7) moves to A7 (V7) and resolves to Dm (i), one of the most fundamental sequences in jazz-minor harmony, appearing across countless standards regardless of key.
- Is Em7b5 easier to play than D#m7b5?
- Yes, considerably — the fingering pattern is identical, but Em7b5 stays in open position with comfortable string spacing, while D#m7b5 crams the same two-finger stretch into the tight, high eleventh fret.
- How does the flattened fifth change the chord's sound?
- It replaces the stable perfect fifth with a diminished one, giving the chord a more unsettled, searching quality than a plain minor seventh, which is exactly the tension jazz composers want at the start of a minor-key turnaround.
- Does Em7b5 ever appear outside minor-key ii–V–i contexts?
- Yes — it relates closely to the diminished triad Edim, since half-diminished and fully diminished chords built on the same root share several notes and often substitute for each other in denser jazz voicings.
- Why is this exact chord family so central to jazz harmony?
- Half-diminished seventh chords let composers signal minor-key harmonic motion with more color and forward pull than a plain minor triad, and because the ii–V–i pattern transposes identically to any key, this one shape pays off across an enormous amount of jazz repertoire.
- Is Em7b5 common outside jazz-influenced guitar playing?
- Less so — its specific tension and function are most useful in jazz, Latin-jazz, and some more harmonically adventurous singer-songwriter material, appearing rarely in straightforward rock, pop, or folk guitar parts.
