Melodic Minor

Melodic

    Just like an M requires us to climb as we write it (up the M, up the mountain)…
When ascending in pitch, the Melodic Minor Scale (from the Natural Minor) is created by raising the 6th and 7th

Flat 3rd 3
Sharp 6th # 6

A Melodic Minor Ascending

Another way to look at it is using the parallel Major scale:
If we use the major scale, when ascending, we flat only the 3rd

Flat 3rd 3

 

Welodic

In Classical Melodic Minor, the ascending and descending sequence of notes change
The Descending pattern follows a Natural Minor

The Melodic Scale in descending scale is different from the ascending scale. 
When we flip an M, we get a W
   W starts at the top, and slides down hill.

In Jazz Melodic Minor, the notes don’t change, regardless which direction the scale is approached.

A Melodic Minor

* A leading tone, responsible for creating tension, is when the seventh scale degree is only a semitone away from the root note.
