Guitar arpeggio

C Augmented Guitar Arpeggio

C Augmented is a three-note arpeggio built from C, E, and G#. It is also commonly called C Augmented Triad. Use it to study chord tones, interval formulas, and guitar fretboard positions.

How to read this arpeggio

The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent C root notes, while circular markers represent the remaining tones in the arpeggio.

Use the interactive fretboard to locate the C root notes and connect the remaining augmented chord tones across standard tuning.

This same arpeggio shape is also commonly called C Augmented Triad.

Chord construction and defining tones

3E
#5G#

C augmented combines 3 (E) and #5 (G#). Stacked major thirds create the raised fifth and divide the octave symmetrically.

Harmonic use

Use this arpeggio over Caug, an augmented dominant sound, or a moving harmony where the raised fifth leads upward by a semitone.

Practice this arpeggio on guitar

  1. Play the C Augmented arpeggio from one C root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
  2. Sequence 3 (E) and #5 (G#) in major-third cycles and notice how the same fingering relationships repeat.
  3. Build a C augmented phrase that resolves the sharp fifth upward to a chord tone in the next harmony.
