What is the G7 Chord?
If you’re learning the piano, you need to know dominant chords and their variants.
The reason that you have to understand these chords is the fact that variants are typically transitions toward different chords. If you want to have any songwriting ability, you’ll need to know how chords change and move toward one another.
An essential tool in this process is the G7 chord. We’ll go over that chord today and explain a little about how you can make it work for you like the greats did .
Understanding the G7 chord
The G7, or G7 dominant chord is comprised of four notes. It’s root, the G chord is made up of just three notes. The G chord is made up of G, B, and D. Playing those notes will give you the G major chord, which is something you likely already know.
The G7 is created when you add the 7th, the F chord, to the top or bottom of that chord. The introduction of a dominant chord into a chord progression usually means that the song is moving toward a different chord. One extremely common transition of the G7 is to the C chord.
If you are in the key of C, try playing a G chord for a few bars, a G7 chord for a few bars, then resolve to the C major chord. You’ll find that the notes are drawn to each other. The introduction of a transitional chord like G7 exposes the fact that music has a natural trend and desire to move one way or another.
Different Forms of 7th Chords
As you progress toward a deeper understanding of music theory, you’ll need to know how different chords work into others . You should start by understanding the major scale. If we start in the key of C, you can imagine each whole step in the octave holding the number that corresponds to its letter.
If C, for example, were the first note in the key, then C would have the number 1 associated with it. 7th chords are relatively easy to create when you keep this in mind. The major C chord would be comprised of the 1, 3, and 5 notes in the scale.
The 7th chord, as we’ve discussed above, is only one note away. The C7 chord would be comprised of the 1, 3, 5, and 7 notes. That’s why it’s called the C7. You can imagine the seventh as being one whole step below the root note of the chord.
In the case of the G7 chord, the 7th that you add is going to be the F note. In the case of C7, the 7th note that you add will be B. When you imagine chords in this numeric way, they become a lot easier to envision and understand. Don’t forget the a7 chord and b7 chord, ok!
Want to Understand Music Theory?
A whole world of improved playing and a greater appreciation of music opens up when you learn a little about music theory. That being said, understanding the G7 chord is a walk in the park when compared to some of the harder stuff.
You have to start somewhere, though, and we’ve got all the information you need if you’re looking to learn.
