How to Play Aaug on Piano
The A Augmented chord sounds suspended and eerie. It stacks 3 notes: A – C# – E#.
Two stacked major thirds. It divides the octave evenly, so it sounds equally at home — and equally unresolved — in several keys at once.

Where it sits
One note of this chord (C#) is on black keys, so play it a little further back on the keys than an all-white shape.
Press all 3 keys at the same time. Keep your wrist relaxed and your fingers curved. The blue dots on the piano below show exactly which keys to press — they turn green when you play the right note.
