What D major is built from
Counting up in semitones from D:
| Note | Interval | Semitones from root |
|---|---|---|
| D | root | 0 |
| F♯ | major third | 4 |
| A | perfect fifth | 7 |
Move all three of those the same distance and you get the same chord on another root — that is what the major triad formula 0 – 4 – 7 means.
How to play D major
Leave the low E and A strings out. The D string rings open. Nothing is higher than fret 3, so it sits in first position.
All four strings are played. The A string rings open. Nothing is higher than fret 2, so it sits in first position.
Play D, F♯ and A together. That is two white keys and one black.
Numbers in the grids are frets. Where a number is printed beside a grid, that is the fret the top row stands for; otherwise the thick bar at the top is the nut. A circle above a string means play it open, a cross means leave it out.

D major on the stave
The same three notes written on a treble stave, spelled the way a major triad is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads D, F♯ and A, and not the same sounds written some other way.
Which keys D major belongs to
| Key | Relative minor | Degree |
|---|---|---|
| D major | B minor | I |
| G major | E minor | V |
| A major | F♯ minor | IV |
Each row is a key whose scale contains every note of D major. A major key and its relative minor use the same seven notes, so the chord belongs to both.

D minor is its parallel: same root, same fifth, and only the third between them.
