What are the chords in the key of F sharp major and G flat major? We will take a look at the basic triad chords and four note chords (with sevenths) in these keys. I decided to combine these two keys together because they are enharmonics of each other. These means that on your piano, the same keys are played. The note, F sharp is an enharmonic of G flat and is the note between F and G.
Let’s start by looking at the F sharp major scale. What are the notes in this scale? They are F# G# A# B C# D# E#. Each of the basic chords in the key of F# is named after one of these notes. In other words, each note forms the root of one of the chords.

The same applies to the key of G flat major. The notes of the Gb major scale are Gb Ab Bb Cb Db Eb F.
The chords in any major key follow the pattern Maj min min Maj Maj min dim (major minor minor major major minor diminished).
The triad chords in the key of F sharp major are F# major, G# minor, A# minor, B major, C# major, D# minor, and E# diminished. When you add sevenths to these chords, this gives you four note extended chords, namely F# major seventh, G# minor seventh, A# minor seventh, B major seventh, C# dominant seventh, D# minor seventh, and E# minor seventh flat five.
As for the key of G flat major, the triad chords are Gb major, Ab minor, Bb minor, Cb major, Db major, Eb minor, and F diminished. When you add sevenths you end up with the four note chords, Gb major seventh, Ab minor seventh, Bb minor seventh, Cb major seventh, Db dominant seventh, Eb minor seventh, and F minor seventh flat five.
Roman numerals are used to represent each chord.
