The C augmented chord (C+) is a C Major chord, with a raised 5th. It contains the notes C, E and G# (G double sharp).
Each note of the C augmented chord is separated by an interval of a Major 3rd. Because every interval inside the C 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 augmented chord:
- The C augmented chord contains the notes C, E, G#
- The E augmented chord contains the notes E, G#, B# (B sharp is the same as C)
- The G# augmented chord contains the notes G#, B#, Dx (D double sharp, which is the same as E)
