Here is a quick guide to chords in the key of F# or Gb minor.
| 1st | 2nd | 3rd | 4th | 5th | 6th | 7th |
| Minor | Dim | Major | Minor | Minor | Major | Major |
| i | iiº | III | iv | v | bVI | bVII |
| F#m | G#º | A | Bm | C#m | D | E |
The notes of an F# minor (natural) scale are:
| 1st | 2nd | 3rd | 4th | 5th | 6th | 7th |
| F# | G# | A | B | C# | D | E |
Written as Gb, this would be:
| 1st | 2nd | 3rd | 4th | 5th | 6th | 7th |
| Gb | Ab | Bbb | Cb | Db | Ebb | Fb |
However, because of the improbable note names (double flats, in particular), this version of the scale is more theoretical than practical, and would almost always be written as F#.
Natural Minor Scale Formula
The scale notes above follow the 'natural minor' scale formula of 'steps':
WHOLE – HALF – WHOLE – WHOLE – HALF – WHOLE – WHOLE
Or 'tones':
TONE – SEMITONE – TONE – TONE – SEMITONE – TONE – TONE
Or even, on a guitar, frets:
Two frets – One Fret – Two Frets – Two Frets – One Fret – Two Frets – Two Frets
Which gives us the following interval relationships from the tonic (1st note):
- Union
- Major 2nd
- Minor 3rd
- Perfect 4th
- Perfect 5th
- Minor 6th
- Minor 7th
- Octave
All the chords in the key of F# minor are made up of notes from the F# minor (natural) scale.
The relative major scale of F# minor is A major.
