# Altered Scale

The altered scale is the 7th mode of the melodic minor scale

What is the melodic minor scale?
This scale constitutes of
R 2 b3 4 5 6 7 R

For example a C melodic minor scale will be

C D Eb F G A B C
If we were to start off this scale from the 7th note and end at the 7th note it will be
B C D Eb F G A B

### Tonic Solfa Version

(ti doh reh moh fah sol lah ti)

This scale becomes a B altered scale
The difference between this scale and the locrian scale

(7th mode of the major scale) is the #2

Therefore Altered Scale Will Be:

R b2 b3 3 b5 b6 b7 R

B altered scale

R = B
b2= C
b3= D
3= E
b5= F
b6= G
b7= A
R= B

Application of This Concept

The altered scale is applied over an altered dominant chord.
The B altered scale above can be used over any B altered dominant chord

e.g B dom 7 #5

LH                  RH
B                   A Eb G

Having B altered dominant which is your 7th chord that takes you to the 3 on the key of C

LH                    RH
B                      A Eb G 7
E                      D G C 3

The B altered scale serves as a passing scale to the 3 chord on the key of C..

Bass               LH                 RH
B                  A Eb G            B altered scale
E                  D G C              E G C

Note: You could run the scale up the keyboard or down the keyboard
Also, the altered scale could also serve as a 5 dominant passing scale to the 1 chord
In the key of C, the 5 is G

Altered Scale: R b2 b3 3 b5 b6 b7 R

Therefore a G altered scale will be

R= G
b2= Ab
b3= Bb
3= B
b5= Db
b6= Eb
b7= F
R= G

Bass             LH                      RH
G                 F B Eb                 G altered scale
C                 E G C                  E G C
