The Ionian, Lydian and Mixolydian modes.


This question has been asked, very often.

Your best bet is to check that, but I will provide a few:
Minor Pentatonic
Blues Minor Scale
Natural Minor
The Phrygian, Dorian or Aeolian (same notes as the natural minor) and Locrian modes
The Harmonic Minor is in vogue these day's also.

I'm a sucker for the Melodic (jazz and classical), and Neapolitan minor scales also.

The Diminished (Whole half, or half whole) scale sounds really good too.
