What E♭aug is made of

Eb Augmented (Eb augmented) is built from the notes Eb, G, B, with the interval pattern 1, 3, #5. A common augmented chord across many styles.

Stack 1, 3 and #5 on a root of E♭ and you get Eb, G and B. 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 E♭aug.

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 E♭ rather than its enharmonic equivalent.
