B chords with alternative bass notes
B major 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. B/A should therefore be read as B Major chord with an A note in the bass and B/G as B Major chord with a G note in the bass.
