7th Chords Explained In Full

7th chords allow you to add a new dimension to your harmony in your songwriting. In addition, they also create a function: Dominant movement in music.

What’s a Dominant Chord mean?

Well, the dominant note in a kay is the Fifth (5th) scale degree. So for example, if I’m in the key of C, then my dominant chord is G. The thing is, that a dominant chord has a seventh note of the scale in it. So the fifth of C would actually be played as a G7 chord = The harmony in this chord is ‘G-B-D-F’.

Seventh Chords have a Flattened seventh in them. Understand that, and notice how the F in the G7 chord is F natural – NOT F#

    What do you mean when you say, “So the fifth of C would actually be played as a G7 chord = The harmony in this chord is ‘G-B-D-F’.” Why not just a G if the G is the dominant chord and you said that the dominant chord already contains the 7th? And what do you mean when you say the harmony is g b d f? Sorry to bother you, but I need to know! haha…

    Also why do you say ,”Seventh Chords have a Flattened seventh in them. Understand that, and notice how the F in the G7 chord is F natural – NOT F#” What does that have to do with anything?

    Forget these two questions. Basically the dominant chord is the 5th of the key… and that chord must contain the flat 7th.. so you turn the G in the key of c into a g7… meaning the 5th is g7 not g natural.. correct?
