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 major 7 chord tones across standard tuning.
This same arpeggio shape is also commonly called Bb Augmented Major Seventh or BbAugMaj7.
Chord construction and defining tones
Bb augmented major 7 is defined by 3 (D), #5 (F#), and 7 (A). It combines an augmented triad with the natural seventh for a bright but unsettled extended sound.
Harmonic use
Use this arpeggio over BbaugMaj7, major-seventh sharp-five chords, and melodic-minor harmony that supports both the raised fifth and major seventh.
Practice this arpeggio on guitar
- Play the Bb Augmented Major 7 arpeggio from one Bb root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Sequence 3 (D), #5 (F#), and 7 (A) through multiple positions and resolve the sharp fifth and major seventh by semitone.
- Improvise over BbaugMaj7, balancing the symmetrical augmented triad with clear resolutions to the root.
