The modes of the Melodic Minor scale (Super Locrian, Lydian b7, etc...) lead to some great sounds.

Look at my Melodic Minor Primer at my lesson site: http://lessons.mikedodge.com

That will start to put the sound of the MM scale in your head.

Then for real examples download the Power Tab transcription I did for the "Common Sounds Found in Jazz" tutorial. That's covers using the MM modes, modes, partical scales, the Whole-tone scale, the H-W scale, combining scales, substitutions, etc...

There's a key subject to get familiar with "substitutions". Substitutions are where a lot of the secrets are. Knowing chord theory s the best way to learn scale, and why you use a certain scale when you do. If you read through that tutorial the "chords" section will show you a number of ways to substitute on the song that I used for demonstration.

You'll see a whole other palette to to paint with...since substituting chords means implying more scales or sounds.

Check it out, it'll be worth your time if you want to know a few of the secrets/common ways people continue to make music.

Sometimes less is more. Take a look at the Lydian tutorial and the Dominant Pentatonic tutorial. Those with show you how to cut down on the number of notes in your scale so you automatically introduce wider Intervals to your playing. And, it will help you sound less scaley, but will help you imply, or cover, more scales by using less notes.
