When to Use the B Augmented Seventh Arpeggio
Play the B Augmented Seventh arpeggio whenever a B Augmented Seventh chord appears in a progression. Unlike scales (which include passing tones), arpeggios guarantee every note you play IS a chord tone, making your solo sound harmonically precise and intentional.
Arpeggio vs. Scale
The B Augmented Seventh arpeggio uses 4 notes (B, D#, G, A#) while the full scale uses 7. The arpeggio is a subset — think of it as the skeleton of the scale. Practice alternating between the arpeggio and the full scale to develop a melodic vocabulary that mixes chord tones with passing tones.
How to Play B Augmented Seventh Arpeggio on Ukulele
On ukulele, find B around fret 2 and play through the arpeggio tones (B, D#, G, A#). You may need to move beyond a single chord shape to reach all 4 notes. Practice connecting the arpeggio tones smoothly across adjacent fret positions.
The B Augmented Seventh arpeggio has a symmetrical, ethereal quality built from major thirds. It fits over Baug, B+, Bmaj7#5 chords and is useful for creating a sense of upward motion and harmonic ambiguity.
Practice Routine
Play the B Augmented Seventh arpeggio as whole notes over a backing track or drone on B. Focus on intonation and tone quality for each of the 4 notes (B, D#, G, A#). After a few passes, begin improvising short melodic phrases built from these arpeggio tones, connecting them with passing notes.
Ukulele Tips
The ukulele's re-entrant tuning creates natural voice leading within the B Augmented Seventh arpeggio. Experiment with picking patterns that take advantage of the high G string to create unexpected interval leaps within the arpeggio shape.
