Slash chords
Chord charts write inversions with a slash: C/E means play a C chord, but put E at the bottom. The chord before the slash, the bass note after it. Change nothing but the bass note and the same chord leans differently.
Same chord, three bass notes
One C major triad up top; only the bass note moves: root, then third, then fifth.
Why bother: the walking bass
The whole point of slash chords is a bass line that moves on its own. Here the bass walks straight down, C B A G F, while plain C, G, Am, F chords ride above. G/B and Am/G are the two slashes doing the smoothing.
