That sound came from a small gray half-globe, about forty centimeters in size, in the hands of a charming lady who was joyfully playing music. Being curious, Régis approached her. She showed him this amazingly singular object, the Hang Gubal. It was invented at the same time as the Hang Bal, about forty years ago by Felix Rohner and Sabrina Schärer, Swiss nationals. On closer inspection, he discovered 7 circle drawings on the surface. It was like a wink of the Little Prince and his 7 planets. In no time at all, he now knew that would be the sound of . It would be heard in the "teaser", the trailer, the documentary, the installation, during cultural debates, and during the opening ceremonies. Hang Gubal and Hang Bal would have a place of honor in .
