The F# dominant 7th chord consists of the notes F♯, A♯, C♯, and E.
Understanding the F# Dominant 7th Chord
A dominant 7th chord is a four-note chord known for its distinctive, often bluesy or jazzy sound, and its natural tendency to resolve to another chord. For the F# dominant 7th (often written as F#7), these four notes are built upon the F# root note.
The Notes and Their Intervals
Each note in the F# dominant 7th chord serves a specific harmonic function relative to the root note, F♯:
- F♯ is the root of the chord.
- A♯ is the major third, creating the major quality of the chord.
- C♯ is the perfect fifth, providing stability to the chord.
- E is the minor seventh, which gives the chord its dominant (7th) quality and adds a unique tension.
Here's a breakdown of the notes and their intervals:
| Interval | Note |
|---|---|
| Root | F♯ |
| Major Third | A♯ |
| Perfect Fifth | C♯ |
| Minor Seventh | E |
Inversions of F# Dominant 7th
An inversion of a chord means rearranging its notes so that a note other than the root is in the bass. The F# dominant 7th chord has three main inversions:
- First Inversion: The major third (A♯) is the lowest note, with the notes arranged as A♯ C♯ E F♯.
- Second Inversion: The perfect fifth (C♯) is the lowest note, with the notes arranged as C♯ E F♯ A♯.
- Third Inversion: The minor seventh (E) is the lowest note, with the notes arranged as E F♯ A♯ C♯.
These inversions offer different voicings and smooth transitions when moving between chords in a musical piece.
