D♯aug

D♯1F𝄪3A𝄪♯5

Two major thirds stacked. Symmetrical: every note can be heard as the root.

Written the other way round it is E♭aug — the same twelve keys on a piano, a different piece of notation.

What is true of it

D♯aug is D♯, F𝄪 and A𝄪 — 1, 3 and #5 counted from D♯.

F𝄪 and A𝄪 are double sharps, and they have to be: every letter from D♯ upwards is used once, so the 3 cannot be written any other way.
