Seventh chords
by: Peter

Hello,

These are seventh chords - also called dominant seventh chords.

To make the seventh chord you need the triad of the letter name - so for G7 you need the triad of G (G, B, D) then you add a minor seventh from the bottom note - in this case that would be G to F.. so G7 has the notes G, B, D, F.

In E7 it would be the triad of E (E, G#, B) plus the minor 7th from E which is D... so E7= E, G#, B, D

Hope this is helpful!
