When to Use the A Suspended Fourth Arpeggio
Play the A Suspended Fourth arpeggio whenever a A Suspended Fourth 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 Suspended Fourth arpeggio uses 3 notes (A, D, E) 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 Suspended Fourth Arpeggio on Charango
Locate A on your instrument and play through the 3 notes of the Suspended Fourth arpeggio (A, D, E) slowly, ensuring each tone rings clearly before connecting them at speed.
The A Suspended Fourth arpeggio avoids the third, creating an open, unresolved sound. It works over Asus4, Asus2, A7sus4 voicings and is perfect for creating a modern, ambiguous harmonic feel that neither commits to major nor minor.
Practice Routine
Practice the A Suspended Fourth 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, 4P, 5P) in any register.
Charango Tips
Practice the A Suspended Fourth arpeggio on your instrument at a slow, comfortable tempo, focusing on clean articulation of each of the 3 tones before gradually increasing speed.
