It's time to analyze Quadad Chords just like we did with Triads.

Can we please have the answers to the exercise portion of this lesson where we are to write out the notes in the E Major Diatonic Quadads? I’m having trouble analyzing the notes in each chord to work out what chord type is on each scale degree. Specifically, dealing with the root notes as a sharp. Thanks!

I think I just cracked the code
does it almost follow the Diatonic Chord Progression of Major-Minor-Minor-Major-Major-Minor-Diminished? but instead of that, it’d be Maj7-Min7-Min7-Maj7-7-Min7-Min7b5?
EDIT: I just got to the Diatonic Quadad Chord Progression and man do I feel smart

Here is a clue …
Justin’s template
You are comparing the chord notes with the major scale of each chords root note.
E major scale = E, F#, G#, A, B, C#, D#
Quadad = E (1), G# (3), B (5), D# (7) = 1, 3, 5, 7 = maj7
F# major scale = F#, G#, A#, B, C#, D#, E#
Quadad = F# (1), A (b3), C# (5), E (b7) = 1, b3, 5, b7 = min7
From earluer lessons you should be able to complete the major scales for all root notes of the quadads and decide if the notes within the quadads match exactly or are modified (by flattening).
G# major scale =
A major scale =
B major scale =
C# major scale =
D# major scale =
I hope that helps.

Yes indeed.
Smarty pants you are!
Have a gold star.
I got confused because of the page layout in ‘learn more’ . For the first four chords the text is adjacent to the relevant chord diagram. From the V chord on though, the text next to the chord diagram is for the previous chord. It just needs an adjustment to the layout.

@netwiz Have you posted in the correct topic? I have looked from top to bottom of the learn more and there are no chord diagrams.
I used the wrong term but this is what I mean
The texts ‘ok so now we’ll look at the IV chord’
and
‘so the chord built from the 4th degree …’
both relate to the diagram under the first of those, knocking the rest of the text+diagram pairings out of sync.
The text ‘so the chord built from the 4th degree…’ is alongside a diagram for the V chord, and this mismatch continues.
Above these, the text always relates to the diagram that it is aligned with.

@netwiz. got it. Thanks for clarifying. I have gone in and made edits to the layout and minor changes to the text format too. Hopefully it is easier to read and follow now.
