The ABBA rhyme scheme gives Donne's poem a measured tone that serves as something like a respectful yet gleeful triumph over the anthropomorphized "Death." 

Death be not proud, though some have called thee
Mighty and dreadfull, for, thou art not so,
For, those, whom thou think'st, thou dost overthrow,
Die not, poore death, nor yet canst thou kill me.

Donne also uses alliteration, first to impart a tone of gravity:  "Much pleasure, then from thee, much more must flow."   Then, again, to convey a tone of triumph in the final lines:  "short sleep" and "wee wake,' and most importantly, the last line, "death, thou shalt die."
