The two genres that do not follow the basic triangle plot pattern are fantasy and Science Fiction. They can often omit one or more parts or even have multiple parts in the triangle plot pattern because of their surrealistic subject matter.
While there is a relationship the Möbius strip, the basic structure that Escher used for the stairs and floors follows the Penrose triangle, or "impossible triangle," first designed by the mathematician Roger Penrose.
Music doesn't NEED structure per-say. You can have a functional musical piece that is one movement followed by any number of others without any sort of refrain or chorus. However, most music does follow some sort of pattern (for simplicity's sake, I'll use pop-music terminology) of verse-chorus-verse-chorus (or verse-verse-chorus, or any number of permutations of this form). This has been the trend because people respond to it, it has an aesthetic quality that people find appealing, but is not necessary. Many free-form/improve pieces do not follow this pattern.
Actually, there are two: The Sitar, a stringed instrument introducing the Raga, the basic tonal pattern of the piece; and the Tabla, a drum, establishing the basic rhythmic pattern.
The melody controls the feel which dictates the rythms of the accompaniment.
