The dominant 7 is used in almost every song.
It is mostly used on the 5th degree of a key.
In the key of "C" that would be the "G" chord.
Let's create the G dominant 7
The term dominant refers to the 5th note of the major scale of each key.
It is called dominant because it is second in importance to the first scale degree, the tonic.
The dominant chord creates an instability that requires it to resolve to the tonic or root of the key.
Example: G7 to C major in the key of C
----There are many exceptions to that rule. The Beatles "Day Tripper" for example uses E7 and A7 for the verse.----
When you created the major 7 chord you used the 7th note of the major scale.
The dominant 7 chord uses the 7th note of the major scale, but lowers it by a semi-tone.
It is a flat 7th note,the Bb note in this case.
Start with "C Dom7" .
Strum this chord as in previous lesson, one strum per chord.
