Welcome to the world premier of the Third Origami Symphony! Just as in a musical symphony, an origami symphony is an elaborate composition in usually four movements of various themes and styles that flow together. This symphony encompasses favorite origami themes of Dinosaurs, Dragons, colorful Australian Birds, and Dazzling Diamonds. 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 presents a quacking chorus of Dinosaurs, including a Tyrannosaurus, Triceratops, and Stegosaurus. The second movement of colorful Australian Birds include a Spangled Drongo, Red-necked Avocet, Collared Kingfisher, and White-Bellied Sea-Eagle. Dazzling Diamonds and Majestic Dragons fill the third and fourth movements. All are of varying levels of difficulty and structured as a symphony in four movements. First Movement: Allegro: Quacking Chorus of Dinosaurs. Second Movement: Andante: Colorful Australian Birds. Third Movement: Minuet of Diamonds with a Trio of Dimpled Diamonds. Fourth Movement: Presto: Flight of the Dragons.
