What Baug is made of
Baug (B augmented) is built from the notes B, D#, G, with the interval pattern 1, 3, #5.
Stack 1, 3 and #5 on a root of B and you get B, D# and G. 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 Baug.
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 D♯ rather than its enharmonic equivalent.
