Notes

F# - A# - C#

The F# Major chord contains 3 notes: F#, A#, C#. It is built using the following intervals from the root: Root, Major 3rd, Perfect 5th. On the piano keyboard diagram above, the highlighted keys show exactly which keys you need to press to play this chord.

How Is the F# Major Chord Built?

A major triad is built using three notes: the root, a major third (4 semitones above the root), and a perfect fifth (7 semitones above the root). This combination of intervals is what gives major chords their characteristic bright and stable sound. The formula can be remembered as: Root + 4 half-steps + 3 half-steps.

Starting from F#, the notes of this chord are: F# (the root), A# (the Major 3rd), C# (the Perfect 5th).

What Key Is the F# Major Chord In?

Every major chord serves as the I (tonic), IV (subdominant), or V (dominant) chord in different keys. For example, if this is the C major chord, it appears as the I chord in C major, the IV chord in G major, and the V chord in F major. Knowing which keys a chord belongs to helps you understand its role in chord progressions.
