All the Chords in the Key of C | Don't Skip this Lesson!

i had the same question... Thanks for asking and thanks for explaining.

Hi Rob, thanks for the great teaching! I must confess I'm a bit confused by the "flat third" you mention à 6'40'', when describing an other way to play a Dm in second position: you play an F on the fourth string, fret 3, and call it "a flat 3rd", and an F on the 2nd string, fret 6, calling it "a minor third". Unless I'm mistaken, of course^^. Is there a real difference? Thanks for caring!

That does make sense! Thanks for breaking it down like that Rob. I think for folks like me who are a bit newer to the theory, it helps to diagram this out on paper, and then you see the relationships. Recently was learning the super-cool progression from "Just the Two of U" which uses these chords just in a different key. Thanks again and hope the little one and family is doing great.

Hey thanks Raf, great to hear from you. I love answering this question, as I still remember when the concept of harmonizing scales clicked for me. Basically, every note within each of the 7 chords needs to be found in the root scale, in this case the C major scale. The dominant 7 of that G7 chord is an F, which is in the scale. If we were to play the 5 chord as a maj7 chord, we’d have an F#, which would be out of key. So, the notes in the chords must be shared with the root major scale. I hope that makes sense. Let me know if it clicked.

Hey Rob, great lesson, thanks so much. One question - can you help us understand why a G7 (dominant 7) was used instead of Gmaj7? The other major chrods seemed to be Maj7, so just curious about the music theory behind that.

Thanks for this Rob sorry was away till Sunday morning looks very helpful

Hi Rod, great lesson

Hi Rob, Have you got the same lessons for other keys? This is a really useul lesson. Thanks!

Great question. In previous lessons I’ve taught how to harmonize the major scale using just basic triads - majors, minors and diminished chords. In this tutorial, we are taking the next step, adding a forth note to each chord. These extra notes are also found in the root scale (C Major Scale), and produce extra flavor.

Hi Rob, I have a question. Why are you using all 7th chords instead of just the major and minor chords? Thanks!

Good lesson
