Violinist - Lang

This is Violinist by Robert Lang, from The Complete Book of Origami: Step-by-Step Instructions in Over 1000 Diagrams (1988). The book is considered a classic in Origami, and has continued to remain in print unchanged. I purchased it from the World's Biggest Bookstore in Toronto back in 1989, and was instantly amazed by the high level of detail of its models. Because many of the models are made from unusual shapes with unusual angles (I swear one model requires a protractor) to this day I still haven't folded everything from it. However, despite the unusual difficulty, these models are original and well worth folding!

This model is from Chapter 5: Action Folds. The chapter contains models that move when you push and pull. This model actually plays violin when you pull the head from the hip.

The model is folded from a 1:1.414 proportioned rectangle. Of course, measuring such a rectangle is difficult, so with this model (and others) I found a way to let the folds determine the exact proportions I needed. Start with a slightly taller landscape rectangle than needed, and then in steps 3 and 4, use the valley/kite fold to determine how much of the bottom edge you need to cut off the paper (because when you're done, the corner will neatly line up with the crease in the diagram). That procedure works every time. For this model, I cut a 25cm square of Origami paper to the correct size, and then folded it with the coloured side in.
