If I got a song goes C-Am-F-G(chord order)
how should I solo along with it.
should I play Pantatonic Scales C major then A minor
then F major and G major at last.

OR should I just play Pantatonic Scales C major or A minor ONLY!!!
then as the music goes on I play the C note, A note
,F note and G note following order (C-Am-F-G)
can you understand what am I talking about?
Please help me out~!!!
