Arpeggio vs. Scale
The A Dominant Seventh arpeggio uses 4 notes (A, C#, E, 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.
