Intro

Hello, here we will put the rest of the music theory concepts not already covered in other note sections.

Major and Minor, Inverse Direction Up Or Down Thirds + Modifying Solfege

Intro

Noticed I'm having trouble translating major to minor solfege. So lets define it.

Good way to remember, is do the opposite of the direction you are going.

Going down from major to minor? Go up and modify

Going up from minor to major? Go down and modify

Visualizing Translation Side To Side


Do Major:       Do Re Mi Fa Sol La Ti
La Minor: La Ti Do Re Mi Fa Sol

Do Major:       Do Re Mi  Fa Sol La Ti
Do Minor: Do Re Me Fa Sol Le Te 

So whats the trick? The one we need to focus on is the second one so lets put it vertically instead


    Do Major    Do Minor

        La   <->   Do

        Ti   <->   Re
        
        Do   <->   Me
        
        Re   <->   Fa
        
        Mi   <->   Sol
        
        Fa   <->   Le
        
        Sol  <->   Te
        
        Ti   <->   Do
        
        Do   <->   Re

So whats happening here. This is a two way function. Give the context of a key, a single note can mean 2 separate solfeges.

Major Down To Minor: Up and Modify

To translate from major to minor, you need 2 steps

1. Go Up A Third

Ex:

   Sol -> Ti
   Re -> Fa 

2. Modify Solfege To Minor, (Mi La Ti, Me La Te)

Ex:
              Instead is
  Do  ->  Mi              Do  -> Me

  Fa  ->  La              Fa  -> Le
 
  Sol ->  Ti              Sol -> Te
        

Minor Up To Major: Down and Modify

To translate from minor to major, you need 2 steps

1. Go Down A Third

Ex:

  La <- Do

  Ti <- Re

2. Modify Solfege To Major Version, (Me Le Te, Mi La Ti)

Ex:
              Instead is
  Sol ->  Me              Sol -> Mi

  Do  ->  Le              Do  -> La

  Re  ->  Te              Re  -> Ti 

Translating Voices With Numbers Instead

To translate numbers instead, its simple. Just the same up/down triad rules. You just have to remember that these represent minor solfege. So 3 -> Me, 6 -> Le, 7 -> Te.


    Do Major    Do Minor

        6   <->   1

        7   <->   2
        
        1   <->   3

        2   <->   4
        
        3   <->   5
        
        4   <->   6
        
        5   <->   7
        
        6   <->   1
        
        7   <->   2
