For the most part, the rhyme scheme of Vikram Seth's "A Doctor's Journal Entry" is written in rhyming pairs. The first fifteen paired lines rhyme. Then, the thirty first line does not rhyme with what should be its pair. Following this line, the rhyme rhyme pattern continues.
The rhyme scheme of the poem begins, for the first ten lines, as follows:
a a b b c c d d e e f f
It continues this way until it reaches the thirty first line where the rhyme is a singular "p." Following this, the poem continues with its previous rhyme scheme.
To explain how a rhyme scheme is created, one must look at the final word in every line of poetry. In this poem, the first two lines end with "warm" and "form." Since these words rhyme with one another, they would bot be given an "a." The following two lines end with "suddenly" and "me." These words rhyme with one another, yet not with the previous pair. Therefore, they are given a "b."
