E7 chords with alternative bass notes
E7 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. E7/C# should therefore be read as E seventh chord with a C sharp note in the bass and E7/A as E seventh chord with a A note in the bass.
Theory: E7/C# could be seen as an inversion of E13 with the ninth and the eleventh omitted. E7/A could be seen as an inversion of E11 with the ninth omitted.
