Master the C# aug Guitar Chord with Interactive Practice
Looking for C augmented, one fret lower? Visit Caug.
Spelled C#, E# and G##, C#aug is the C# augmented chord, with the root, major third and raised fifth above its root. All 3 voicings are fretted and none rings an open string; one is a barre shape.
Every interval between neighbouring notes is a major third, which is why the chord sounds symmetrical. For lead lines, reach for the C# whole-tone scale: it holds each note of the chord, so every chord tone is available. E# and G## are unusual spellings, which is why the same sound is also written Dbaug.
The player at the top adds a drum loop with a tempo you set, which is a simple way to play along and rehearse chord changes.
C# augmented guitar chord is also written as C#aug, C#+, C#(#5) or C#maj(#5).
