When to Use the A# Dominant Thirteenth Arpeggio

Arpeggio vs. Scale
The A# Dominant Thirteenth arpeggio uses 6 notes (A#, D, F, G#, C, G) 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# Dominant Thirteenth Arpeggio on Ukulele
On ukulele, find A# around the open strings and play through the arpeggio tones (A#, D, F, G#, C, G). You may need to move beyond a single chord shape to reach all 6 notes. Practice connecting the arpeggio tones smoothly across adjacent fret positions.
The A# Dominant Thirteenth arpeggio outlines a dominant seventh chord, creating the tension that wants to resolve. Use it over A#7, A#9, A#13 chords, especially in blues, funk, and jazz where dominant harmony drives the groove.
Practice Routine
Practice the A# Dominant Thirteenth arpeggio in different octaves, starting low and working up. Then try displacing the octaves — play the root low, the D an octave higher, and continue leaping. This trains your ear to hear the intervals (1P, 3M, 5P, 7m, 9M, 13M) in any register.
Ukulele Tips
The ukulele's re-entrant tuning creates natural voice leading within the A# Dominant Thirteenth arpeggio. Experiment with picking patterns that take advantage of the high G string to create unexpected interval leaps within the arpeggio shape.
