I'm noticing modes such as the Dorian b5 and the Lydian b3. Does this mean to simply flatten the 5th and 3rd intervals respectively?
Yes. So you simply play your dorian mode but instead of hitting that perfect fifth, you'd hit a diminished fifth (tritone).

Thanks, that helps a lot!

lol, now play a dorian flat second or a lydian flat fifth

i think there must be some confusion with that one.... Lydian b3rd was mentioned in the first post, which should actually be Lydian #2nd which is a mode of the harmonic minor.
there is already a major third in this scale and the 2nd is raised.

Lydian b5th would appear to be a confusion??? (correct me if i'm wrong:cool because it definately isn't a regular mode.

EDIT - before anybody takes this info as gospel.... give me an hour to check it! there is contrasting info on the net about the Lydian mode of the harmonic minor, so i'm just working it out now

re-edir - no, i was correct... Lydian #2nd is correct, not Lydian b3rd
here is what i used to work them out, for your reference these are the modes of the harmonic minor
