Dominant 7th Chord

The Dominant Seventh Chord is built on the fifth scale degree of the major, harmonic minor and melodic minor scales.  The major triad (root, third, fifth) and minor 7th (10 half steps from root to seventh) create a distinctive sound that is universally linked to the dominant function.

There are three inversions to a Dominant 7th Chord.

When the root of the chord is the lowest sounding factor (the Bass voice in 4-part writing), the chord is in Root position.  

When the third of the chord is the lowest sounding factor (the Bass voice in 4-part writing), the chord is in 1st inversion.  

When the fifth of the chord is the lowest sounding factor (the Bass voice in 4-part writing), the chord is in 2nd inversion.  

When the seventh of the chord is the lowest sounding factor (the Bass voice in 4-part writing), the chord is in 3rd inversion.
