This question makes a load of silly and unnecessary assumptions about the composition of Shakespeare's sonnets. How do we know that anything ever "called him back" from working on sonnets? It could well be that he got an idea for a Sonnet, then wrote it down immediately, then delivered it to someone, perhaps, and that was all. There is no reason to suppose that Shakespeare wrote the sonnets with a view to having them published in one volume in 1609; rather the contrary, I should think.
But even if one were to suppose that his composition of a sonnet was interrupted by something, why in the world should you suppose it was always the same thing? Can we not imagine something like this:
Shakespeare: Shall I compare thee to a bale of hay? Thou art more scratchy . . . no, that's no good.
Heminges: Will! Come here!
Shakespeare: Just a minute, John. Shall I compare thee to a lousy play? Thou art more profitless . . . no! No!
Heminges: Everyone is going to the tavern for a drink. Want to come? Don't mope around here. What a waste of a summer's day!
Shakespeare: All right, all right . . .hmm, "summer's day"? Oh well, I can get back to that later.
sonnets
some of them were called sonnets
Yes, it's in my book which is called "Shakespeare's Sonnets"
In addition to his plays, he wrote a series of poems called the Sonnets of Shakespeare
They are called sonnets
Shakespeare wrote over 154 of these poems which are called sonnets.
Sonnets. Sonnet XVIII, for example.
Shakespeare didn't publish any sonnets. He wrote 154 sonnets which were all published during his lifetime but they were never published by him. Two of them were published in a volume called The Passionate Pilgrim by Isaac Jaggard in 1599. All 154 were published in a volume called "Shake-speare's Sonnets" in 1609 by one Thomas Thorpe.
It was originally called "Shakespeare's Sonnets" and was first published in 1609. It has since been reprinted many times, sometimes under the same title, and sometimes as part of a "Collected Works" anthology.
Shakespeare's sonnets are known by numbers, written in Roman numerals. Therefore three of them are Sonnet I, Sonnet II and Sonnet III. Or you can pick any three numbers up to and including CLIV.
Shakespeare's poem's are called Sonnets. Consisting of lines of a,b,a,b,c,d,c,d,e,f,e,f,g,g. hope this helped.
They don't have to be; but it is understandable that people might think of them that way. The reason is that throughout history, some of the most famous sonnets have been about love, especially certain sonnets written by William Shakespeare. Among Shakespeare's many sonnets about love are Sonnet 18 ("Shall I Compare Thee to a Summer's Day"), Sonnet 105 ("Let Not My Love Be Called Idolatry"), and Sonnet 130 ("My Mistress' Eyes Are Nothing Like the Sun"). I enclose a link to a site that has all of his sonnets.
