How to Play A7 on Piano
The A Dominant 7th chord sounds restless and bluesy. It stacks 4 notes: A – C# – E – G.
A major triad plus a flattened seventh. The tritone between its third and seventh is what makes it lean so hard toward the chord a fourth above.

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 4 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.
