When to Use the D Major Seventh Arpeggio

The D Major Seventh arpeggio uses 4 notes (D, F#, A, C#) 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.
