Riu (River). A natural flow of water that moves across the Earth’s surface, driven primarily by gravity. Its course is constantly shaped by the terrain, the volume of water and the obstacles it encounters.

The water moves forward, but never in exactly the same way. It changes speed, direction and form, while maintaining a continuous flow.

Music also moves forward and gradually transforms: one note gives way to another, a pattern repeats with subtle variations, a texture grows or dissolves.

The river and music share this continuous movement: they flow, transform and follow their course.
