How deep is the red

Is this is not a pretty tale?
Is this not a riddle?
A bow shoots arrows through the air
A bow drags notes from a fiddle
But who is the beau of poor girl's dreams?
That a king may send to battle

Is this not a pretty tale?
Is this not a riddle?
If red is the breast of soldier's tunic hung with a silver medal
And red is the thorn that protects the rose, a deeper red than the
petal
How deep is the red our redeemer bled, the debt of our sins to
settle?
How deep is the red?
How deep is the red?
How deep is the red our redeemer bled?
How deep is the red?
