The bandoneon is a kind of small accordion that was born in Germany. Later it was taken to the Rio de la Plata region in South America. From there, it spread all over the area, specially in Argentina and Uruguay. It has become a symbol of the tango. In this link from wikipedia you can read the history of this beautiful instrument.
I have used the bandoneon for the fifth music in my Jazz Band. Here he is:
It all starts in Zaragoza back in 2013, visiting the amazing Eric Joisel's Exhibition. There I discovered the bandoneonist for the first time. The thing that really caught my eye was the instrument. The way the bellows are folded is simply astonishing. Take a look at Joisel's fold:.

Coming to fold this model was very straightforward, specially compared with previous models. Both, dwarf and instrument CPs where published and available in Internet. For the dwarf, I used Ricardo Montecinos' 'Dwarf with Skirt' CP. You can find it in his web page. As in my previous dwarves I have replaced Ricardo's CP head pattern with the 'tradicional' pattern to ease the collapsing process. The final CP I used is this:

For this dwarf I have used Kozo paper as always. The square is 65x65 cm, the largest possible size from the sheet of paper I had. You can see now some photos of the folding process:
Closing the back of the model is very straight forward if you have already folded the 'traditional' dwarf. It follows the same technique. You can see it in my post about THE CLARINETIST.

Finally you have to dampen the model and harden it with methylcellulose or carpenter's glue. Then you have to let it dry.
In the previous photograph you can see how the legs come from the back side. You have to fold them forward and strenghten them with glue so that they can support the weight of the model.
Some more modelling and it is done:
The instrument, a bandoneon, it a little origami jewel. A handmade CP draft was released by Joisel himself::
Later on, Ricardo Montecinos redrawed the CP with the computer. You can see it in his web page:
Setting the Crease" blog by Australian Peter Whitehouse (Wonko). It has more than 400 entries, most of them belonging to his wondrous 365 Project. He folded a different model every single day of the year 2011. And not easy ones, just hold your breath and take a look. In one of his entries he has a photodiagram on how to fold this model. It seems he also fell in love with it as I did.
I started from a 32x20 grid, kozo paper. Size of the paper 20x12,5 cm. I painted it with brown water colour. Here are some photos of the folding process:

|First I precreased the CP except in the central area. There, I only precreased the horizontal and vertical lines. The triangles and diamonds are more easily folded later.|

|And we arrive to the finished model|
|The final model is not perfectly closed . We can help it with a little carpenter's glue or methylcellulose. The purists can try to close it simply with wet folding techniques.|
