About the question "Most rock guitarists find it easier to solo using the minor scale"but what if the song is in
C major chord~doesn't it sounds bad when you play a
"minor" scale?(except Am scale.cuz Am=C).

and another question is that while I am using Am scale
to solo C-Am-F-G. do I have to reach ,first C note,A note
,F note and then G note? kind of following order?
cuz every time when I soloing along a song.I just feeling
like I am "practicing" ~I am not even have the feeling
of playing music.~. so please help me out.
