I'm looking to broaden my knowledge on any applicable exotic scales outside the standard major and minor classical scales, but I'm struggling to find the names of these scales I'm attempting to learn. The scales I'm looking for sound like the bass lines Steve Digorgio seems to play quite a bit, and can be applied in some metal compositions. An example would be his bass solo in Cosmic Sea () it starts at 02:34. The best word I can use to describe the kind I'm looking for is 'exotic', maybe 'arabic', 'egyptian' and 'indian' will give you an idea of the sound I'm trying to get. So far I only know the standard harmonic minor scale and the hungarian minor scale. Any input on things I should look up to get this exotic sound would be greatly appreciated. Thank you!
