It doesn't matter what the sculpture is called or how complicated the artist thinks it is. I'm sure you can disassemble it by following these simple instructions in the given order.
First, focusing on the larger piece, align the other piece's gap so you can move it rightward from the upward pointing triangle to the downward one. Then, with the critical piece's non-gimmicked nut fully lowered, slide the narrow section of the other piece (where the sculptor's copyright is) past the nut. You should notice that one of the two little bar ends on your piece's end curl is squared off versus rounded, which gives you enough clearance to untwist it from the other piece's identical curled end and leave it hanging from that piece's middle. Next, turn the sculpture so that the larger piece is vertical, side on to your vision, and slide it past the violin shape. With the notches on the other two pieces (labeled with one dot and three dots) aligned, you can pull the (formerly middle) piece past them and out, facing you with the open side up. Finally, arrange the two “ocean wave” shapes on the two pieces into the two curves on the other and remove the critical piece with the tiny hanging loop (but otherwise identical), making sure the tiny loop is in the upper left.
