Hi @oliviackl! it is always nice to know that the music that one plays, has generated some kind of emotion in the other. The instrument to the right of the video is a "Palo de Lluvia" (Rain Stick) or "Palo de Agua" (Water Stick). This is a hollow bamboo cane with seed filling, inside which sticks of bamboo or wood stick, forming a helicoid that extends all along. When the stick is gently tilted the pebbles or the seeds fall and its pounding with the sticks produces a sound that resembles rain or water falling. Its origin dates back to the indigenous peoples of the South American Amazon, however, archaeological remains have been found in pre-Inca cultures of the Peruvian coast and the central Andes. It is generally used to create ambient sound effects or as a percussion instrument.
