Guitar Chords in F Sharp Major
Diatonic Triads and Major Scale
The guitar chords in F sharp Major are F#, G#m, A#m, B, C#, D#m, E#o (E sharp diminished).
In this set of chords, we will move the B shape (based on the A form) to the C# Major chord at the 4th fret, and then to the D#m (fret 6 - with flatted 3rd), and the F# shape (based on E Form) to the G#m (fret 4 - but with a flat 3rd).
The E#o is a decent fingering for a diminished chord.
There are 6 sharps in the key of F sharp (F#). The sharps are F#, G#, A#, B, C#, D#, E# (everything but the B). Note that the key of F has only 1 flat (B flat) - this is the 'opposite' of the key of F# (what is sharped in F# is natural in F).
Remember the total amount of sharps and flats for keys with the same core letter name (half step away) always equals 7. In this instance, we have 6 sharps (in F#) + 1 flat (in F) = 7. See Circle of 5ths.
The Major Keys: C G D A E B F# Gb Db Ab Eb Bb F

It is time to:
- Fret all of the guitar chords in F sharp. Get comfortable with how the all work and feel. Notice that the fingerings or voicings chosen for this key are base on the E form (I, ii, iii, viio) and the A from (IV, V, vi).
- Practice the scale. Notice you have a choice where you play the B tone. I've colorized the B to draw attention to this.
- Play the Chord Scale.
- Play progressions, such as I-vi-ii-V7-I.
- Write your very own progression from the guitar chords in F sharp. Make it sound the way that makes sense to your ear.
We could say that the key signature of F# is 2 Naturals: B and F (E# is F), but good luck keeping friends. Just a note here to say that you can think about tone groupings (keys) in different ways than the circle of 5ths. Of course, the key of F# is the same tone set as the key of G flat (Gb).
It is very interesting that just by naming this key something different, it changes its color or mood. Check it out yourself (like everything).
Is there a way to remember this stuff?
Always, always look for relationships between guitar chords: similarities and opposites.
Example: the chord A minor is composed of the tones a, c, and e. If we want A# minor, sharp everything - a#, c#, e#. Same for D minor; D# minor is d#, f#, a#.
Another: G#m is g#, b, d#. Gm is g, b-flat, d. 'Opposites.'
