Improvisation — pop in C, relative scale
The C-G-Am-Em progression is in C major, but you improvise over it with the A minor pentatonic: the same shape, the same fingerings as on a minor blues. That's the relative-scale trick: A minor and C major hold exactly the same notes, only the centre of gravity shifts. In practice, one scale shape learned once serves two families of tunes. The trap: play the pentatonic like a blues and it sounds minor and sad over a bright pop groove. The work is right there, same notes, different anchor.
Tips
End your phrases on a note of the current chord, not on A: that's what tips the ear toward major.
Over C and G, aim for the scale's C and G; over Am and Em you can lean on A. The colour shifts with every chord.
Record yourself: on playback you hear at once if a phrase sounds bluesy where the tune called for sunshine.
