Melodic Minor Just different Positions?

So the Melodic Minor scale have the same patterns as the major scale but only in different positions and starting on different root notes????

the melodic minor (descending) is the notes of a major scale but you start on the 6th and end on the 6th, think of it kinda like a mode. but yes your right

Like nater2 said, you can think of it as something similar to a mode, because scales are modes and Melodic Minor is a scale/mode... Basically to get the Melodic Minor ascending, you flat the 6th and 7th of the minor scale you're playing. So, A Aeolian/A Natural Minor would now include F# and G#, thus making it A Melodic Minor (Ascending). Melodic minor descending is the same as the root scale, so there is no difference.

Dont you just love the crazyness of scales and modes.....

Has me baffled often, then its like a light comes on and its like 'ohhh yea'....
