Transpose down a perfect fifth

[Ryan Michael]

Hello . I have a score that I would the entirety of to be transposed down a perfect fifth.

I tried

\Transpose c f,{

 E4 e f g g f e d c c d e e4. D8 d2 r2

}

But that was greater than a fifth.

Then I tried 

\transpose c f{

%ibidem%

}

But that also didn't work ...
