Major Scale 7th Chords in All 12 Keys

This reference chart lists 7th chords that naturally occur in each of the 12 keys of the Major scale, along with the individual notes that make up each 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.
