I like to see a pivot chord(s) for modulation in the palette ?

I am still fighting with the modulation in HN2
It is also a keyfeature, but it seems not easy ( for me) to achieve
For instance as example i like to modulate from Cmajeur to Gmajeur( 1 # )

( it also valid for all 24 scales in the circle of fifths diagram in HN2, ( white and black keys on the keyboard ..so i pick one Cmajeur scale and the neighbour G majeur scale)

- it is possible to see the shared chords "choose scale Cmajeur in the Circle of fifths diagram and than via Ctrl+Gmajeur
But than you have to decided what chord will be acted as a pivot chord??

For Cmajeur(source key) to G major(target key) you choose Aminor

------------------------------------------------------------

The rule is that the dominant of the target key leads us to that key

And the tonic cannot be used as a pivot chord? --> find out ?

------------------------------------------------------------

a general form is Isource-?-Vsource- PIVOT CHORD!-Vtarget-?-Itarget

Isource------------Vsource------ ..scale Cmajeur

                                            PIVOT    

                                            -------Vtarget -----------------Itarget ..scale Gmajeur

Despite the fact that you in HN2 you can see shared chord between two scales it is up to you what chord you choose a pivot chord

My idea is that HN2 must come up with a pivot chord..  Cmajor and Gmajor share for instance  4 chords ( triads )

S 

-----------------------
So when you are working with the palette you must use the basic chord layout than
_____________________________ 

I am not sure about this... after study 2 examples of C majeur  to Gmajeur and F major it seems that there 4 pivot chords occur

To generalize this to other scales ?

--------------------

Note: yes 4 pivotchords !! and i checked this with the two scales in HN2 : open a Cmajor palette and a second with Gmajor

and you start with I and go to VII  ladder position fin Cmajor that in the Palette for Gmajor shows 4 pivot chords
I think this is valid for the whole circle of fifth diagram for major and minor scales (24 scales ) (outer and inner circle)--> there will be always 4 pivot chords? if you take a random key and go to the left or right target key of the circle of fifth diagram (on outer or inne circle

(note this evening i will listen to Inner circle music too!)

I think it is better on forehand to know what are the pivot chords for the whole circle of fifth for 24 diatonic scales
This knowledge must be programmed into HN2 to give a easy start with modulation

But you have to focus yourself  on the rule that the dominant of the target scale leads us to the pivot chord

WELL IT SEEMS ME TO HANDY THAT HN2 COMES UP WITH A SUITABLE PIVOT CHORD FOR MODULATION

I try to come up here on the forum with a list of 24 pivotchord for all 24 diatonic scales..later..but i think it is easy to deduce the general case from example 1
- all 12 major scales do have the some chordformulae  1111/2111/2 in the circle of fifths  

- all 12 major scales do have the same chord types

From one example Cmajor to Gmajor is the Aminor ( Amin=VI forCmajor and Amin=II forGmajor)

Take the Amin(II) of the target key G and the dominant as orientation for the modulation

============================================================

(1) So for all 12 major keys modulation in the outer circle of the circle of fifth diagram take the the Amin(II) as pivot chord of the target key and the the dominant from this key as orienation for the modulation 

===============================================================

(2) As i study a example for a C major to Aminor (relative minor key of major) it seems that for this type of modulation, the C chord (iii)  is used as pivot chord
So for all 12 major keys to their respective relative minor chords take the C (iii) as pivotchord of the target key and use the dominant from these keys as orientation fore the modulation
Try this out?

=================================================

As you study the circle of fifth and take the Cmajor than it is surrounded by one key what does have the same notes as Cmajor namely Aminor ( does have the same chords).

The other 4 keys =scales around Cmajor differ only in one note ..they have 6 notes in common with the Cmajor  ..so how this modulation works?..what is the pivot chord for this?

Recap: so the the Cmajor is surrounded by (Fmajor, Dminor, Aminor, Eminor and Gmajor)
If i can modulate ( find the pivot chords) for the 5 scales surrounded Cmajor than i can compose

So there are a number of modulation cases ( 5 i think) to examine ..and i did (1) and (2)
At the moment i do know 2 of them ( major scales to major scales modulation and major scales to their relative scales modulation) and they use the Amin and C as pivot chord 

How about the other 3 cases :

- C ->Dm

- C-> Em

-Am -> Em

To see this i made here below a diagram ( unfortunately the diagram is not complete ..i cannot make a slope connection line for the the crosslines )
So i must made a diagram in Fireworks dreamweaver  and post here.

So when i study Cmajor who is surrounded by 5 scales in the circle of fifths i can modulate the outer circle with the Major scales( use II as pivotchord from the targetscales )
Than i can modulate the relative scales from the major scales too ( use iii as pivotchord from the targetscales)

Let me try to make a diagram here for the pivot chords from a part with Cmajor as starting point in the circle of fifth

 As you noticed in the diagram not all modulations are done

- the modulation for the innercircle of the circle of fifths (minor scales ) ...e.g if you want to modulate from Am to Em ?

- how about F to Am , C to Dm , C to Em and G to Am ?

All those modulations here must have a suitable pivot chord, because there scales differ only one note  ( 1b,1# or no sign)
There is one thing to more consider and that is the direction of the modulation?

I go from C to G and than from G to C..how about the pivot chord?

   F -- II -- C -- II -- G

   |               |            |

  iii              iii           iii  
   |               |            |

  Dm --?-- Am--?-- Em

Pivot chords :   II = Aminor and  iii = C

  You can see that i can modulate the major scales with their relative scales by using those pivotchords from the target scales

(use the rule that the dominant chord of the target scale leads us the pivot chord)
So if you do this with the palette in HN2 than you will see as you take for example Cmajor -> Gmajor that the Aminor from Gmajor is the pivot chord( this chord connect the Cmajor scale with the Gmajor scale )

Examples

1- Cmajor(source key)-> Gmajor (1#)(target key) = Aminor pivot chord

C: I-IV-V^7 I   vi (=pivot chord Am) SOURCE KEY

                 G : ii (=pivot chord Am) V^6_5- I -ii^6 - V^7 -I   TARGET KEY      

This chord progression is constructed by hand with the voice leading principles! and no HN2 used
But how to replicate this HN2 ?? 
I like the idea from cognitone that the cumbersome handwork of chords voiceleiding is automated by HN2 

If voiceleading is not anymore the issue than you can concentrate on the composing  

Exercise try to this modulation for yourself in HN2

2 Gmajor -> Dmajor(2#) = ?? ..=Amin(II) for Dmajor(2#)
