The V7 Chord is the only chord that has complete freedom in music theory. RULES OF THE CHORD V7 …….. NOT RULES CAN
The V7 chord supports all tones chromatically, which means, a V7 chord can be used with any melody tone. The melody in the chord doesn’t have to have any tones, really in jazz or high-level arrangement, we try to get these “color tones”. This is the only possible chord that chromatically supports all extensions.
Use the V7 cord as a replacement cord. A replacement chord is a chord that is inserted into music or replaces a chord in music. Why? Because we want to fill our music with interesting combinations, color tones, or just fill empty spaces.
RULE …….Aon its V7 cord may be preceded by a chord. The V7 is the easiest replacement to learn and use.
EXAMPLE of using a V7 chord as a replacement chord.
Here is the original music: Dm7 | FM7 | CM7 |
Now let ‘s add the V7 representation chords: A7 Dm7 | C7 FM7 | G7 CM7
Here’s the fun now! V7 cords can be placed before the V7 cords. CM7 | E7 A7 Dm7 | G7 C7 FM7 | D7 G7 CM7
How do I use these cords? 1. These chords are perfect for empty recurring bars moving back to the verse or into the chorus. Use V7 cord embedding to go back to IM7 cord. Example: You have 2 repeat bars entering the CM7 chord in measure 1, use E7 A7 | D7 G7. 2. Place V7 chords under the melody. This will also fill in measures that only have 1 or 2 plus chords that will give you that jazz sound. Example. let’s play Twinkle Little Star
MELODY: | CCGG AA G- | FFEE | DDC |
CHARTS: C — | FG- | FC- | GC- | Now let’s add V7 representation chords:
CHORD: C- G7 C7 | F G7 C C7 | F G7 C A7 | D7 G7 CM7- |
Notice in batch 2 I added the G7 chord and the melody is on note A. Here is an example of changing the chord to get a jazz sound, the melody note A is the 9th of G. Here we try to fix it and in jazz, using color tones instead of 1-3-5 of the chord. 3. Improvising a V7 chord: Since the V7 chord is the only chord that supports all extensions, 9th, 9-, 10-, 11, 11+, 12-, 13, 13+, you can improvise on any note of your choice. In Classical Music it is the same, composers can use any melody tune against the V7 chord.
Here are some tips for playing the V7 chord in the left hand: 1. As a composition chord play F, A FLAT, BD (7, 9-, 10, 12) OR F, G, A, B, D (7, 8, 9, 10, 12) 2. As a Three-Tone Quarter, (great for the blues) F, B, E (7, 10, 13)
This article is pretty simple, but I found out if it is possible to get an overall picture first, then we can backup and learn step by step. The V7 chord is part of our lessons on adding representative chords to organized piano and jazz lessons at
