so far ive been listening to alot of blues and also a whole chunk of steve vai when it come to phrasing.
be it funny, sad, angry, happy...thats phrasing for you. its how you put your emotions on your guitar. scales is just one of the many ways to go about it.
i depend alot on my technique to phrase. currently im doing alot of percussive picking to get that angry/sad feeling. i use small legato runs to impose watery/smooth/sleek tones.
its the technqiue. its all about your personal preference.
effects can help too. i depend alot on my vox wah for those funkyy feelings.
cheers
