Voicing and expanding dom7th chords

 Dominant 7th voicing

Practicing or keeping up with your craft is something everyone should be doing or focusing on. For musicians that would be working on out theory and our practical. Today we worked on a new craft or topic which was voicing dominant 7th chords.

When going from the dominant 7th to the tonic, the leading tone in 5(7th) resolves to the tonic. The leading tone is created from the tonic and with the leading tone you should always take advantage of the common chords. It stabilizes the the chord progression. 

This pic shows the inversions of a seventh chord and what's in the bass. In root position with the root in the bass the figured bass is 7. First inversion is the 3rd in the bass which is 6 5. Second inversion would be 4 3 with the 5th in the bass. The third inversion is the 7th in the bass. With inversions you must not double the third but you cant triple the root. 

With seventh chords you can sometimes omit the fifth interval in the chord and you can also triple the root when omitting the fifth.  In a dominant 5 7th 3rd inversion chord you must always resolve to a 1 chord and in a 5 7th first inversion must always resolve to root 1. 

Within the chords you have tendency notes which are 3 and 7th of the chord. The 7th resolves down a step and the 3rd resolves up a step. Anytime you have a 5 chord moving into a 1 chord it is considered a complete chord. A complete chord can go into a incomplete.
