E♭ harmonic major
E♭1F2G3A♭4B♭5C♭♭6D7
Major with a flattened sixth: the mirror of harmonic minor, and the reason a major key can borrow a minor subdominant.
The same sounds spelled from the other side are D♯ harmonic major.
Written out
Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.
