The other day I was discussing memorizing things with a friend who noted that I have an exceptionally good memory. This is a gift that has served me well throughout my life: it helped me become "scripture chase champion" (meaning that I could identify a passage of scripture based on one or two key words, then recite it verbatim, more swiftly and more accurately than anyone--what an accomplishment!) when I was in high school; it helped me memorize the discussions in Chinese as a missionary; it helped me get through a bachelor's degree with really great grades and a minimum of studying.
Some things are especially easy to memorize--certain poems or songs, for instances. One of the easiest poems to memorize is This Be the Verse, a bitterly funny poem in iambic tetrameter with simple diction and a straightforward ABAB rhyme scheme. TBtV is one of my favorite poems ever, and my very favorite poem by Philip Larkin, a curmudgeonly British poet whose attention to the intracacies of rhyme and form contrast nicely with a very earthy vocabulary and a sensibility keenly aware of loss. (As Robert Hass writes in Meditation at Lagunitas, "All the new thinking is about loss./ In this it resembles all the old thinking.")
Consider, for intance, Larkin's poem "Sad Steps." It begins with the line, "Groping back to bed after a piss," an occasion that provides the speaker with a view of a brilliant moon. The poem becomes a meditation on the fact that the moon's "wide stare"
Is a reminder of the strength and pain
Of being young; that it can't come again
But is for other undiminished somewhere.
Larkin doesn't seem like a particularly nice person but he wrote wonderful poetry, even if he is known as the poet of dirty words. If you aren't familiar with his work, check it out.
