Arpeggio vs. Scale
The A Minor Ninth arpeggio uses 5 notes (A, 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.

This 5-note arpeggio (A, C, E, G, B) benefits from economy picking, combining sweep and alternate picking motions. Practice isolating two-string pairs to build coordination before linking the full shape.

Start by playing the A Minor Ninth 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.
