The F sharp augmented chord (F#+) is an F sharp Major chord, with a raised 5th. It contains the notes F#, A# and Cx (C double sharp).
F#+ is effectively the same chord as Gb+.
The note ‘C double sharp’ (Cx) is actually enharmonically the same as D, but the because the augmented chord contains a raised 5th, it is more accurate to refer to this notes as C double sharp, in order to correctly indicate that it is a C sharp that has been augmented (raised by one semitone).
Each note of the F sharp augmented chord is separated by an interval of a Major 3rd. Because every interval inside the F# 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 F#+ chord, the new chord will contain the same notes as the F# augmented chord:
- The F# augmented chord contains the notes F#, A#, Cx (same as D)
- The A# augmented chord contains the notes A#, Cx, Ex (that’s E double sharp, which is the same as F sharp)
- The D augmented chord (same as Cx) contains the notes D (same as Cx), F#, A#
Some Quick F#+ Chord Theory
- The F# augmented chord contains the notes F#, A# and D.
- The F#+ chord is produced by playing the 1st (root), 3rd and sharp 5th note of the F sharp Major scale.
- The F sharp 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).
- F# augmented is an F# chord, with the C# raised to Cx.
- The F sharp augmented chord resolves naturally to the B minor or B Major chord.
