B dominant 7th chord
How to play B7 on piano
The B7 chord is B D♯ F♯ A: B (root), D♯ (major 3rd), F♯ (perfect 5th), A (minor 7th).
Spread four fingers over the four notes, thumb on B in the right hand and the little finger on B in the left.
Each inversion moves the bottom note up an octave. Practicing them in a row teaches your hand the same chord in three or four shapes, so you can reach it from wherever your hand already is.
