Crescendo

(Annie Are You OK)
(Will You Tell Us That You're OK)
(There's A Sign In The Window)
(That He Struck You-A Crescendo Annie)
(He Came Into Your Apartment)
(He Left The Bloodstains On The Carpet)
(Then You Ran Into The Bedroom)
(You Were Struck Down)
(It Was Your Doom)

I don't understand how the term Crescendo fits the lyrics above.

–noun
1.
Music.
a.
a gradual, steady increase in loudness or force.
b.
a musical passage characterized by such an increase.
c.
the performance of a crescendo passage: The crescendo by the violins is too abrupt.
2.
a steady increase in force or intensity: The rain fell in a crescendo on the rooftops.
3.
the climactic point or moment in such an increase; peak: The authorities finally took action when public outrage reached a crescendo.

It ties into the 2nd line of the first stanza:

As He Came Into The Window
It Was The Sound Of A Crescendo
He Came Into Her Apartment
He Left The Bloodstains On The Carpet
She Ran Underneath The Table
He Could See She Was Unable
So She Ran Into The Bedroom
She Was Struck Down, It Was Her Doom
