Analysis of "Break of Day"

Thesis: The sudden use of a break at the end of each stanza illustrates with sound the wrongness of a lover leaving his or her companion immediately at the crest of dawn.

• The change in the meter from the first two rhyming couplets to the last couplet in each stanza causes the reader to stumble somewhat, emphasizing the wrongness and immorality of the conclusion of the stanza and thereby the night.
• In each stanza, the first four lines use iambic tetrameter, as in "Must business thee from hence remove?" whereas the last two lines use iambic pentameter, as in "He which hath business and makes makes love, doth do" (, 17).
• The change in meter towards the end of the stanza sounds improper compared in its abrupt shift, just as the abrupt shift from lover to a person with business is wrong.
• Furthermore, both of them take place towards the end of the event, but not when the event should end: the shift takes place near the end of the stanza, but not quite at the end, and the leaving takes place towards the end of the night, but not quite at the end.
• Similarly, the first stanza shifts from four lines of rhetorical questions to a statement, a shift that similarly emphasizes the contrast between the smooth beginning of the night and its rough ending.
• The rhetorical questions of "'Tis true, 'tis day; what though it be?" last the first four lines, providing a smooth, almost seductive tone to the beginning of the stanza that is interrupted by the implied command behind "Love [...] should [...] keep us together" (1, 5-6). 
• The seductive tone is best illustrated by "why should we rise because 'tis light? / Did we lie down because 'twas night?," because the speaker is arguing persuasively without seeming like arguing, just as seduction is persuasion without seeming to be; this contrasts harshly with the significantly less soft-spoken command-like conclusion
• The difference between the beginning of the night and the end is fully illustrated by the difference between the seductive question and the businesslike command.
• This line of questioning's end follows the same pattern as the metric shift, thus emphasizing the difference between the beginning of the stanza and the end, and thereby beginnings and endings in general.
