One thing I started to do is pick a key, learn the scale formula, apply it to the key, and then bam. I got a new scale to play. So if the key of C is... C - D - E - F - G - A - B - C Then the minor appreggio scale (to my understanding) is... 1 - b3 - 5 - b7 Then the notes will be... C - Eb - G - Bb So just look at it that way... I think it's pretty simple cuz you can apply it to any place of the neck. Edit: O' course I may be wrong, but this has been my understanding of the subject lately.
