Welcome to the world premier of the Seventh Origami Symphony! Structured as a musical symphony in four movements, interesting themes highlight the possibilities of origami. Detailed and distinct reptiles, farm animals, antiprisms, stars, and monkeys combine to create an origami adventure.Contained in this work are 37 original models, each a masterpiece by origami master John Montroll. Each model can be folded from a single square using standard origami paper. The first movement begins slowly with a trio of turtles. After more reptiles, we take a walk through the farm in the second movement. Mind-boggling polyhedra fill the third movement. The fourth movement captures a variety of monkeys singing and hooting from tree to tree.First Movement: Adagio, Allegro: Reptiles Picking up Speed.Second Movement: Andante: Walking Through the Farm.Third Movement: Minuet of Antiprisms with a Trio of Stars.Fourth Movement: March of Boisterous and Frolicsome Monkeys.
