Number of notes: 3
Also known as: aug, +, +5, ^#5
The A Augmented arpeggio contains 3 notes (A, C#, F). Use the interactive fretboard above to explore this arpeggio on Bass with different tunings and fret ranges.
When to Use the A Augmented Arpeggio
Play the A Augmented arpeggio whenever a A Augmented 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 A Augmented arpeggio uses 3 notes (A, C#, F) 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 A Augmented Arpeggio on Bass
On bass, locate A on the E string at fret 5. This compact 3-note arpeggio (A, C#, F) can be played across two strings without shifting, making it ideal for building bass lines that clearly outline the harmony.
The A Augmented arpeggio has a symmetrical, ethereal quality built from major thirds. It fits over Aaug, A+, Amaj7#5 chords and is useful for creating a sense of upward motion and harmonic ambiguity.
Practice Routine
Practice the A Augmented arpeggio in different octaves, starting low and working up. Then try displacing the octaves — play the root low, the C# an octave higher, and continue leaping. This trains your ear to hear the intervals (1P, 3M, 5A) in any register.
Bass Tips
Practice the A Augmented arpeggio on bass using a raking technique across adjacent strings for a smooth, flowing sound. Then try the same shape with a two-finger alternating pluck for a more defined, punchy articulation.
