piano chord
D♯m7
D♯1F♯♭3A♯5C♯♭7
Minor triad with a minor seventh. The same four notes as a major sixth chord a third above.
Written the other way round it is E♭m7 — the same twelve keys on a piano, a different piece of notation.
What is true of it
D♯m7 is D♯, F♯, A♯ and C♯ — 1, b3, 5 and b7 counted from D♯.
These are also the notes of F♯6/D♯ and G♭6/D♯. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
On an instrument that cannot reach all 4, the 5 goes first, in that order.
