D Major uses Scale Form II which has no squeeze shifts and uses one new note–C#–XI on (4) and IX on (1).
Review and visualize the scale:
- Begin with m,i alternation; when comfortable switch a,m (m,a) alternation.
- Maintain legato connection. When descending the scale, strive to have your left-hand fingers in a prepared posture, hovering near the frets before they play.
- When secure, practice the scale while vocalizing the note and watching your hands.
- Finally, play and say the scale one stroke per note from memory.
