Daniel Libeskind is a Polish-born American architect who is widely known for his 'unbuildable' designs. In 2008, he began working with the German company Schimmel Pianos to design a jagged, working, grand piano.
This is the famous (or infamous to some architects) Libeskind Piano. As you can see, it definitely isn't what you think of when speaking of normal grand pianos. Upon looking through the principles and elements of art, I realized it was a lot different with 3D pieces than with 2D.
Obviously, line played a big role to Libeskind in designing this piece. The basis for all of his buildings or furniture, is the jagged deconstructing of everything. He uses line to create those sharp, uncomfortable edges to enhance the fact that this is not your usual boring piano.
The colors of the piano, though it may have been just a coincidence being the normal colors of a piano, are another element which I think add to the strange, awkward feeling you get when looking at (and probably playing) the piano. It also serves to relate it to a normal piano by being a bit similar but then it tares down all normalcy at the same time.
Form is another easily relatable element to use here. To be a little bit more redundant, Libeskind has succeeded in emphasizing that fact that this piano is ridiculously weird and unnatural.
I can never tell whether I truly like Libeskind's designs or if I'm just simply amazed that they could be built in the first place. Like I said earlier, he is known for his almost unbuildable blueprints. Here are some of his other buildings, maybe you can make more of a decision than me.
