The Notes in a C# 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 a C# Augmented chord is C#.

The 3rd

Finding E# from C# step by step:

  • Start on: C#
  • Step 1: move up to D
  • Step 2: move up to D#
  • Step 3: move up to E
  • Step 4: Land on E#
