Bit of a boo-boo here.

The Melodic Minor ascending raises both the 6th and 7th degrees of the scale while going up, then returns them to their key signature position when descending.

I don't know what all the fuss is about. I've never been confused by the system and it works just fine. And is not wrong, it is accurate. It has evolved into a cohesive, highly usable system over the centuries and some pretty high-powered musicians, Monteverdi, Haydn, Bach, Mozart, Beethoven, etc. have found it perfectly good for cranking out masterpiece after masterpiece.

The only musicians I have ever heard criticize the system or try to find things wrong with it are those who have little or no musical education or formal training, and generally tend to be self-taught.

Like folk-type singers (city-billies, rather than actual traditional singers).

P. S. Okay, let the rock throwing begin.
