I was astounded to learn that people in different countries describe the sounds that animals make differently. Drip Drop Drip drop, drip drop, darned rain won't stop. Here's a short poem that popped into my mind one day while sitting on a bench near the railroad tracks in Wayzata, Minnesota. When I hear a choo choo train I think of all the many things that I should do.
Sound poems written by kids are often fun to read.
However, rhythm can be a problem. As you can see, I got the rhythm for the two sound poems above from the sounds themselves. Tick tock, goes the clock. Bow wow says the dog. Quack quack says the duck.
