The major scale is the foundation of Western harmony — seven notes with a bright, resolved sound, and the reference every other scale is measured against. On guitar, the d major scale uses the notes D, E, F♯, G, A, B, C♯ — the diagram above shows every one of them across all positions of the neck, with the root (D) highlighted so you can anchor each shape.
KnowYourNeck turns this into an interactive neck you can rotate through every position, switch between note names and scale degrees, and drill one box at a time with Focus Mode. It's the fastest way to actually learn the major scale instead of just reading a chart.
