The C Augmented Seventh arpeggio uses 4 notes (C, E, G#, B) 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 C Augmented Seventh Arpeggio on Ukulele
On ukulele, find C around the open strings and play through the arpeggio tones (C, E, G#, B). 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 C Augmented Seventh arpeggio has a symmetrical, ethereal quality built from major thirds. It fits over Caug, C+, Cmaj7#5 chords and is useful for creating a sense of upward motion and harmonic ambiguity.
Practice Routine — Exercises for Playing
Start by playing the C Augmented Seventh arpeggio ascending and descending at 60 BPM, one note per beat, using a metronome. Once even and confident, play it in eighth notes, then triplets, keeping each note articulate. Spend at least 5 minutes daily on this before moving to musical application.
Ukulele Tips
On ukulele, integrate the C Augmented Seventh arpeggio into your fingerpicking by plucking through the chord shape one note at a time. This transforms a static strum into a melodic, harp-like texture that showcases each interval clearly.
