The Locrian scale goes from B to B on the white keys:
B-C-D-E-F-G-A-B-C,
the intervals are:
H/W/W/H/W/W/W
(H=Half Step W=Whole step),
so, starting on a C, it would be:
C/Db/Eb/F/Gb/Ab/Bb/C

The Phrygian scale goes from E to E on the white keys:
EF G A BC D E
so the intervals are:
H/W/W/W/H/W/W
so starting on C, it would be:

C/Db/Eb/F/G/Ab/Bb/C-


Both scales have a flatted second, minor third. flatted sixth and flatted seventh, but the Locrian scale has a flatted fifth step -while the Phrygian has a perfect fifth step--

The Locrian scale's tonic chord is the dreaded "devil's triad"C-Eb-Gb, or diminished chord, rather than a major or minor chord, like the other modal scales have, which makes it a difficult scale to do much with--

The Mixoydian is a major scale with a flatted 7th(like a C with a Bb instead of a B) and Lydian is a major scale with a raised 4th(F# instead of F)-

This will probably take a bit of thought to absorb, since it took me the better part of the last hour to write out an explanation, and I (at least supposedly) understand it;-)
