Em chords with alternative bass notes
E minor chords for piano with alternative bass notes presented by keyboard diagrams.
Explanation: The slash in the chord name indicates that the second letter is added as a new bass note. Em/D should therefore be read as E Minor chord with a D note in the bass and Em/C as E Minor chord with a C note in the bass and so forth.
