Triad Chords of the Major Scale in All 12 Keys

This reference chart lists basic triad chords which present naturally in all 12 keys of the Major scale. It also shows individual notes that make up every chord.

I've included one more key, totalling in 13 keys. F# and Gb are enharmonically equivalent keys with same amount of sharps and flats (6). So they have sort of a parity—they are both valid keys. The choice between the two is a matter of notation convenience or convention in a given musical context.

Chords have been derived using the most common type of scale harmonization which involves taking every other note from the scale and combining them to form chords. The resulting chords are referred to as diatonic chords which simply means that they are constructed using only the notes of the given scale. Another common title for such a chart is Chords In Key.
