F#(no3)

F# to C# is a perfect fifth (7 semitones). Only two notes, the root and the fifth C#, seven semitones apart. With no third it is neither major nor minor. On guitar the root is usually doubled an octave up, as in the shapes below. Turned upside down, C# below F# is a perfect fourth and the chord finder names it C# + F#.

F#5 on the guitar

Standard tuning (E A D G B E). Strings run low E on the left to high e on the right, frets downwards; × is a muted string, ○ an open string, and each dot shows the note it sounds, with the root in blue-green. Every shape below has F# as its lowest note.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play power chords on other roots.

Inversions of F#5

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.

Where F#5 fits

A power chord has no third, so it belongs to any key where its root and fifth do and can stand for either F# or F#m. That ambiguity, and the fact that a bare fifth stays clear under heavy distortion where a third would turn muddy, is why rock and metal riffs are built from power chords.
