What Daug is made of
Daug (D augmented) is built from the notes D, F#, A#, with the interval pattern 1, 3, #5.
Stack 1, 3 and #5 on a root of D and you get D, F# and A#. That interval recipe is what makes the chord an augmented chord — move the same shape to another root and the character travels with it, which is why Caug sounds like a transposed Daug.
Augmented: Unsettled, dreamlike; symmetrical.
Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with F♯ rather than its enharmonic equivalent.
