Write a Sonnet in Forty Minutes

A timed exercise with hard stage gates. The point is not to produce a good sonnet in forty minutes; it is to find out which part of sonnet-writing you are slow at, because that is the part you have been avoiding.

Form: Exercise
Lines: 14
Metre: fourteen lines, iambic pentameter attempted, any fixed rhyme scheme, one forty-minute sitting

Worked example: a sonnet written under this clock, uncorrected afterwards

Line numbers

The man who measures windows does not look at what is out there. He has done this years and still he puts his tape along the hook and writes the number down, and disappears. I asked him once what he could see. He said the frame, the sill, a bit of someone's shed. The glass is not his business. His is size, the width, the drop, the thickness, and the rise.

I have been measuring the view instead: the hill, the weather, what the light was like the year we moved. I have not measured the window once. It sticks. It will not strike. So here is what the man with tape would say: write down the size, and fix the view some day.

The clock, in four stages

Minutes 0 to 8: write the fourteenth line. Not the first — the fourteenth. A sonnet is an argument that has already decided where it is going, and writing the last line first gives you the target. Write it in iambic pentameter and make it a complete sentence.

Minutes 8 to 20: write eight lines that set up the fourteenth line without agreeing with it. The octave should establish the position that the last line will overturn.

Minutes 20 to 34: write the four or five lines that get you from the octave to that last line. This is the hardest stage and it is where the timer earns its keep — you cannot afford to sit and admire line 9.

Minutes 34 to 40: read it out loud twice, fix only the lines that do not scan, and stop. Do not revise for meaning today. The revision is a different exercise with a different clock.

Rules that make the exercise work

Use a rhyme scheme you can write in your head: ABAB CDCD EFEF GG is easier to hold than ABBAABBA CDECDE, because the alternating pattern lets you write the even lines a few seconds after the odd ones.

Ban new proper nouns after minute 20. Most stalled sonnets stall because the writer went looking for a better example instead of finishing the one in front of them.

Allow slant rhyme, but only for the last two rhyme pairs. If you allow it in the first quatrain, you will accept the first word that half-rhymes and the poem will have no pressure in it.

What the worked example shows

The specimen is a sonnet whose volta is a reversal of measurement: the window man measures size, the speaker has been measuring view. It was written under the clock, and two lines still do not scan cleanly — the ninth line runs to eleven syllables and the tenth line has an inverted first foot.

Those flaws are left in on purpose. A timed exercise is diagnostic, not presentable: the useful information is that lines 9 and 10 arrived late, in minute 31, which is roughly where this writer always runs out of room. If your slow stage is different — if you always lose minutes 0 to 8 — that is what you now practise, not the whole sonnet.

How to run it a second time

Run the same exercise three days later with a different fourteenth line. Keep both drafts. After four runs you will have a personal split time for each stage, and the stage that is consistently over budget tells you which craft problem to work on next: invention, argument, metre, or nerve.

Terms used in this entry

stage gate阶段门限: A hard deadline that stops you improving one part of a draft while another part is unfinished.
slant rhyme斜韵: A near rhyme, close enough to be heard as a rhyme but not exact.
inverted foot倒置音步: A metrical foot with the stress on the first syllable where the pattern expects it on the second.
target line目标行: The line you write first because it fixes what the poem has to prove.
