There is no such thing (really) as "alliteration poems" -- or "alliteration poetry" -- at least not yet. But our language is forever evolving, and as writers experiment with new forms, who knows? While it does not officially exist today, it would simply be a poem with alliteration in it. Alliteration is the poetic or literary device of repeating consonant sounds. It pleases the ear. It's delightful word play. So why not use it?
Horse riding is a very challenging experience. Especially, if you’ve never ridden a horse before. The first challenge for you is to saddle up your horse. Initially, it is really hard and thrilling to maintain your balance. To control your horse, you have to master special motions, which are unusual for your body. You should sit straight in the saddle and press knees and legs firmly against the sides of the horse. Try to move with the rhythm of its movement. Finally, you will be very pleased and at the same time excited when you will manage with all challenges.
