Cadence

Day time musician night time lover.
Our crimes make a melody, our rhythm runs for cover.
My heart beats to your drum, tempo so fast it's merely a hum.
You know you can't fret up on top of this scale.
Composer lowers his bow and, the crows starts to hail.
Acapulco duet symphony, so exquisitely placed in time.
UN-copyrighted words a jigsaw puzzle that makes up the rhyme.
