What is the fewest number of White chess pieces from the start of a game, that can be placed on a standard chessboard in order to make it impossible to place a Black piece on the board that is not under attack?

Remember,
The final answer must be a subset of the original starting pieces, i.e. only 1 queen, 2 rooks, etc.
Bishops should be on different colour squares.
It is not necessary to attack squares with white pieces on them, as the black piece cannot share a square.

(In reply to The best I could come up with by Sing4TheDay)

I could be wrong, but do you need the pawn that is above/right of the queen?

I think you have a 7 piece solution.
