Circle of Fifths

[musallio]

D / F#-C-E

3rd b7 9th

is this a D7add9 chord? whats the right name for it?

thanks.

Thanx 4 that chord swishmasta.
I think U can call it that..
But I would rather say it's a D9 because there are no 11th, 13ths & what whats

I stand to be corrected though.

You're correct musallio, the chord is a D dominant 9th (D9) chord.  The reason why it's not an add9 chord is because you have that 7th present.  If there was no 7th, then it would be a regular Dadd9 chord.

Thanx T-Block..I've just learnt something once again:

 the "Add" comes in when there is no 7th..
right?

This brings me to the next question:
What would I call a 13th chord with a 9th or 11th in it if the "add" comes in as the result of the omission of the 7th?

Thanks Now I understand Thanks alot God Bless all of you...

Here's one:

Progression using Circle of 4ths

Circle 1:

A / G-C-E           
D / F#-C-E   or   D / F#-B-D#       
G / F-Bb-D           
C / E-Bb-D   or   C / E-A-C#
F / Eb-Ab-C
Bb / D-Ab-C   or   Bb / D-G-B
Eb / Db-Gb-Bb
Ab / C-Gb-Bb   or   Ab / C-F-A 
Db / Cb-E-Ab
Gb / Bb-E-Ab   or   Gb / Bb-Eb-G
B / A-D-F#
E / G#-D-F#   or   E / G#-C#-E#
(and you right back where you started)


Circle 2:

D / C-F-A
G / B-F-A   or   G / B-E-G#
C / Bb-Eb-G
F / A-Eb-G   or   F / A-D-F#
Bb / Ab-Db-F
Eb / G-Db-F   or   Eb / G-C-E
Ab / Gb-B-Db
Db / F-B-Db   or   Db / F-Bb-D
Gb / Fb-A-Db
Cb / Eb-A-Db   or   Cb / Eb-Ab-C
E / D-G-B
A / C#-G-B   or   A / C#-F#-A#
(and you right back where you started)

Now, look at these 2 circles of 4ths.  They look similar, they use all the same notes, but each will sound different because they start different.  The first circle starts with A going to D, but the second circle starts with D going to G.  Can you see the difference?  It's hard to see at first, but you'll get it.

Thanks.  I understand what you're doing in your right hand...But What are you doing in your left??  Is it some sort of pattern to the chords you chose??  I am totally missing it!

The LH hand is moving in 4ths, counter-clockwise on the circle of 5ths.  Check this out:

Circle of 5ths: C-G-D-A-E-B/Cb-F#/Gb-C#/Db-Ab-Eb-Bb-F

Now, contrast that with the circle of 4ths, which is the reverse of that above:

Circle of 4ths: F-Bb-Eb-Ab-Db/C#-Gb/F#-Cb/B-E-A-D-G-C

Now, let's take the progression example I posted and pull out all the bass notes:

A / G-C-E           
D / F#-C-E   or   D / F#-B-D#       
G / F-Bb-D           
C / E-Bb-D   or   C / E-A-C#
F / Eb-Ab-C
Bb / D-Ab-C   or   Bb / D-G-B
Eb / Db-Gb-Bb
Ab / C-Gb-Bb   or   Ab / C-F-A 
Db / Cb-E-Ab
Gb / Bb-E-Ab   or   Gb / Bb-Eb-G
B / A-D-F#
E / G#-D-F#   or   E / G#-C#-E#
(and you right back where you started)

A-D-G-C-F-Bb-Eb-Ab-Db-Gb-B-E

Now, look at those bass notes and compare it with the cirle of 4ths:

Circle of 4ths: F-Bb-Eb-Ab-Db/C#-Gb/F#-Cb/B-E-A-D-G-C

Bass notes: A-D-G-C-F-Bb-Eb-Ab-Db-Gb-B-E

U see any similarities?  Notice that the bass notes from the progression start with A going D, then to G, then to C, etc.  Now, look at the end of the circle of 4ths.  You see where the A goes to D, then to G, then to C, etc.  Aren't they both the same movements?

Circle of 4ths: F-Bb-Eb-Ab-Db/C#-Gb/F#-Cb/B-E-A-D-G-C

Bass notes: A-D-G-C-F-Bb-Eb-Ab-Db-Gb-B-E

Then it keeps going with F to Bb, then to Eb, then Ab, etc.  Coincidence?

Circle of 4ths: F-Bb-Eb-Ab-Db/C#-Gb/F#-Cb/B-E-A-D-G-C

Bass notes: A-D-G-C-F-Bb-Eb-Ab-Db-Gb-B-E

The whole point of learning this circle is to get you to realize that most musical movements is in 4ths.  Knowing the 5ths will help you to stay in key.  For example, u know that in the key of G there is an F# in the major scale.  So, if there comes a point where you are playing a load of F naturals, chances are u have gotten out of the key.

Oops, I meant to say I understand the LEFT hand notes, but not the right hand.  Why did you use those chords??  What is the pattern?

In this exercise, the pattern for the RH chords is:

6 / 1 chord in 2nd inversion
2 / lower the 1st note of the above chord

In C, u would have:

A / G-C-E *6 in bass, 1 chord in 2nd inversion in RH
D / F#-C-E *2 in bass, 1st note lowered from above chord

Then, it switches keys to Bb and does the exact same thing:

G / F-Bb-D *6 in bass, 1 chord in 2nd inversion in RH
C / E-Bb-D *2 in bass, 1st note lowered from above chord

Then, it switches keys to Ab and does the exact same thing.  Every 2 chords, the key goes down a whole step and repeats the process until you are back where you started. 

Side-bar:
Other people may see these as 2-5 progressions, but I don't unless you break up the exercise into 4 chord patterns.
So, the first 4 chords would be a 6-2-5-1, then the key would move down 2 whole steps and repeat the process. Don't ask me why, my brain works different than most people, LOL.

Now, the circle of 5ths is not where I got my chords from.  I got my chords form experimenting with what sounded good with the bass notes and what overall sound I wanted for the progression.

Here's a youtube video I found of a guy explaining key signatures and the Circle of 5ths:

#9 Circle of fifths tutorial; How to draw a circle of fifths (circle of keys)

[rockyaopartner]

At the top of the Circle Of Fifths diagram, the key of C has no sharps or flats. Starting from there and going clockwise by ascending fifths, the key of G has one sharp, the key of D has 2 sharps, and so on. Going counterclockwise from the top by descending fourths, the key of F has one flat, the key of B♭ has 2 flats, and so on.The Circle Of Fifths is used in music theory to represent the relationship between Diatonic Scales. The numbers on the Circle Of Fifths chart show how many sharps or flats the key signature for this scale has. Thus a Major Scale built on A has 3 sharps in its key signature.
