A Dominant 7th Piano Chord
The Notes in an A Dominant Chord
The root is the bottom note of the chord, the starting point to which the other notes relate. The root of an A Dominant chord is A.
The third of an A Dominant chord is C#. The third is up four half-steps from the Root.
Finding C# from A step by step:
- Start on: A
- Step 1: move up to Bb
- Step 2: move up to B
- Step 3: move up to C
- Step 4: Land on C#
- Bb is a minor second above A.
- B is a major 2nd above A.
- C is a minor third above A.
- C# is a major third above A.
The Min 7th
The minor seventh of an A Dominant chord is G. The minor seventh is down two half-steps from the Root.
Finding G from A step by step:

- Step 1: move down to G#
