The Notes in an A# Augmented Chord

The Root

The root of the chord is always the easiest to find because it's in the name of the chord! The root of an A# Augmented chord is A#.

The 3rd

The third of an A# Augmented chord is CX. The third is up four half-steps from the Root.

Finding CX from A# step by step:

  • Start on: A#
  • Step 1: move up to B
  • Step 2: move up to B#
  • Step 3: move up to C#
  • Step 4: Land on CX
