The C sharp augmented chord (C#+) is a C sharp Major chord, with a raised 5th. It contains the notes C#, E# and Gx (G double sharp).

It is most commonly played with the root note on the 4th fret of the 5th string (first shape in the image below).

Each note of the C sharp augmented chord is separated by an interval of a Major 3rd. Because every interval inside the C sharp augmented chord is identical, it is known as a symmetrical chord. Another way of looking at this is as follows – If you play an augmented chord starting from any of the notes inside the C#+ chord, the new chord will contain the same notes as the C sharp augmented chord:

  • The C# augmented chord contains the notes C#, E#, Gx
  • The E# augmented chord contains the notes E#, Gx, Bx (that’s B double sharp, which is the same as C#)
  • The A augmented chord (same as Gx) contains the notes Gx, C#, E#

Some Quick C#+ Chord Theory

  • The C#+ augmented chord contains the notes C#, E# and Gx.
  • The C#+ chord is produced by playing the 1st (root), 3rd and sharp 5th note of the C# Major scale.
  • The C# augmented chord (just like all augmented chords) contains the following intervals (from the root note): Major 3rd, Major 3rd, Major 3rd (back to the root note).
  • C# augmented is a C# chord, with the G# raised to Gx.
  • The C sharp augmented chord resolves naturally to the F# minor or F# Major chord.
