F#7: guitar chord voicings, inversions, scales and arpeggios

F#7 (Dominant 7) is an interactive GuitarArcanum page with chord formula, intervals, voicings, inversions, triads, pentatonic patterns, scales and arpeggios on the fretboard.

Chord formula

Interval formula: 1 3 5 b7. A major triad with a minor 7th. A tense chord that wants to resolve — the engine of tonal music and the backbone of the blues.

Chord tones

Between the major 3rd and the b7 sits a tritone — the source of the tension and the pull. That tritone is what makes it a dominant.

Sound character

Tense but energetic. In the blues it's self-sufficient; in tonal music it pulls to the tonic.

Harmonic function

A dominant (the V). It pulls up a fourth to the tonic. In the blues it sits on every degree.

Typical progressions

G#m7 – C#7 – F#maj7
F#7 – B7 – C#7 (blues)
C#7 → C
