F♯ major chord

Home in F♯ major, and the V that pulls toward B.

How it sounds
Bright and settled. F♯ to A♯ is four frets, and that gap gives it its warmth, while C♯ on top holds it steady. There’s no open grip. The lowest of its five grips is the E form, at the 2nd fret.
Where it lives
The I of F♯ major, the IV of D♭ major and the V of B major. In F♯ major it’s home; in B major it pulls the song back to B. In B harmonic minor it’s the V, and its third, A♯, is the raised seventh that leads back to B. In D♭ major the same chord is written G♭. Rock and pop, mostly in songs in B minor that use it as a major V. Hotel California, in B minor, goes to it straight after the opening Bm.

Voicings across the neck

F♯, A♯ and C♯ can be played in five places on the neck, each built from a different open chord shape. Neighbouring forms share a root, so each one hands over to the next, and together they run from the 2nd to the 14th fret before the cycle starts again. The E form at the 2nd fret is the fullest barre, all six strings. The D form at the 4th uses only the top four, which keeps it small and light.

F♯ major is a root, a major third and a perfect fifth: F♯, A♯ and C♯, taken from the F♯ major scale by skipping every other note. Four then three is what makes a chord major. Turn the gaps round, three then four, and you get F♯ minor: F♯, A, C♯.

What each interval does

In these keys and scales

F♯ major turns up in twelve scales on the site, and the job it does depends on the scale. In F♯ major it’s the I, home. In B major and B harmonic minor it’s the V, the chord that pulls back home. In E♭ minor it’s the III (written G♭ there), the relative major inside the minor key, and as the VI of B♭ minor (G♭ there too) it’s a warm step away from home. The numeral beside each scale names the job, and the name opens that scale’s page.

Progressions

A lot of progressions in F♯ major start on F♯, and nearly all of them come back to it. In I–⁠IV–⁠V the other two chords keep returning to it. In I–⁠V–⁠vi–⁠IV it opens the loop, and B at the end leads back round to it. V–⁠I turns it the other way: there F♯ is the V, and it resolves to B.
