Re: ROCK phrasing
MercyMercy Mercy? Areyouserious? that's gospel, not even close to this typeof rock.
Most of the time a sax in a rock band plays a minor petatonic the whole way up and down with some tricks like growls or whatever, because they're overpayed and dont care.
If you want to be better than that, you can really go to town on this type of stuff. Since it's most likely all dominant chords, it would be the place to fly through some patterns. Try some triad pairs, or whatever floats your boat. Just make it straight and fast.
Also like hexaclon said, rythm is a big part of it. Start your solo out slow, with some interesting rythms and few notes, and then work into the fast stuff. Long high notes also add good effect, if you can hit them without making it sound thin. That's all in the throat.
