Bb Augmented Guitar Arpeggio

Bb Augmented is a three-note arpeggio built from Bb, D, and F#. It is also commonly called Bb 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 Bb root notes, while circular markers represent the remaining tones in the arpeggio.

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

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

Chord construction and defining tones

3D
#5F#

Bb augmented combines 3 (D) and #5 (F#). Stacked major thirds create the raised fifth and divide the octave symmetrically.

Harmonic use

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