Every major chord is the same shape: up 4, then up 3. Try any key.

A major triad is a major 3rd (4 semitones) with a minor 3rd (3 semitones) stacked on top. The recipe is identical from every root note — only the starting key changes. For notes, fingering, and inversions of any specific chord, see the major chord reference, or practice them under time pressure in the Chord Drill.
