LET'S MODULATE TO A DIFFERENT KEY !!!!!

 

First here's some stuff we need to agree on:

 

1.             Chords can be either major or minor

 

2.             Chords can be identified either by letter names or by Roman numerals. If you use Letters you only specify minor chords (by writing a little 'm' ) or diminished (with a little o). Otherwise you presume a chord is major. If you use Roman Numerals usually you show major chords with capitals and minor or diminished chords with lower case.

 

LIKE THIS:

 

in C major

 

I      

      ii   

  iii  

IV 

 V  

vi 

    vii        

      C            

          Dm        

        Em          

         F            

                   

      Am         

Bo

       

 

 

3.                    Cadences are like pauses in the music.Sometimes pauses are like commas,sometimes they are like full

stops :

 

V-I           Perfect cadence                    your music sounds finished

 

IV-I .       Plagal cadence                      again sounds finished. Sounds like Aaaaaa - mmennnnn.

 

V - vi       Interupted cadence              sounds more like a pause. Handy to use before repeating an idea.

 

I Ė V        Imperfect                               sounds like having a rest. Handy at the end of a verse to wind yourself up for a chorus.

 

 

  1. The commonest way to establish a new key is to have a PERFECT CADENCE. Preferably with chord V immediately Before the bar line and chord I immediately AFTER it.

 

OK here's the business. By the way, if you don't understand what I've just said,yell now,because you'll be up a gum tree in a minute if you donít.

 

The most important note in your new key is the LEADING NOTE. This is always the major 3rd of chord V.So to get to your new key you need to find a chord from your old key with that note in,OR one that can be CHANGED to get it.

 

Confusing,huh? It ll get better though when we get going. By far the commonest modulation is to the DOMINANT of the old key.This is easy because the leading note of the dominant key is ALWAYS a MAJOR third of Chord II IN YOUR FIRST KEY. Watch:

DFA

DF#A

D

EGB

EG#B

 

 

 

 So to get from your original key to the dominant:

 

                                                                                                              

 

1.             Get to chord ii       

    Eg in C   

Dm

 DFA

2.             Make it Major.   

 

D       

 D F# A

3.             add a b7 if you like.   

 

D7

 D F# A C

4.             Have a perfect cadence over the bar line in your new key.  

to                            G

G D B

Now get ready for a total modulatory experience!

 

There are ONLY THREE DINIINISHED 7 CHORDS IN THE WHOLE WIDE WORLD!!!

 

 

 Ab                           

 A  

 Bb 

 F                                                

Gb                                            

G  

D  

Eb

E

C#                                                             

 

                                                                                          

                                                                                           

 

1. could be Abo7  Fo7  Do7 or Bo7

 

it could take you off to C Eb F# or A. Minor or major. The worlds you're oyster when you modulate that comp!!!!
