A scale contains the ingredients for many chords. In a major scale, taking alternate scale degrees creates triads: 1–3–5, 2–4–6, and so on.
In C major, C–E–G makes C major, D–F–A makes D minor, and B–D–F makes B diminished. They all use the same scale, but their internal intervals differ.
Try playing only two or three chord tones at a time. You can omit or repeat notes to find a comfortable guitar voicing. Listen to how one voice moves into the next chord.
