B7 chords with alternative bass notes

B7 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. B7/G# should therefore be read as B seventh chord with an G sharp note in the bass and B7/E as B seventh chord with an E note in the bass.
Theory: B7/G# could be seen as an inversion of B13 with the ninth and the eleventh omitted. B7/E could be seen as an inversion of B11 with the ninth omitted.
