This year, the Cartagena International Music Festival wanted to create a tribute to American music: ‘the sound of the Americas’. But, how can we make this concept become something real? We decide to build a music box, and compose ‘the sound of the Americas’.But what is the sound of a continent?We use the mechanism of classical music box. But we replace ‘the roll’ for America, and in lieu of ‘pin’ we use people. Then we invited the entire continent to geo-tag page with its mobile phone or computer. The app transforms every person into a musical note, depending on their location in America. Then, simulating the rotation of the Earth each person became part of ‘the sound of the Americas’.The movement grew through the media and the people who joined each day, gathering 7,123 musical notes around the continent.

We hit upon the idea of using the music box’s own cylinder-and-pin mechanism.By replacing the cylinder inside the box with the Americas, and then arming the cylinder with people instead of pins.We put out a mobile-phone geotag invitation for everyone across the continent,With an app that converted each participant into a musical note based on their location within the continent.The ‘people-pins’ positioned around the Americas set off the notes that made up the 'sound of the Americas', with the rotation of the Americas cylinder, being just like the earth itself,And just like a music box with its pins spinning around and around.The ‘Sound of the Americas’ movement took on a life of its own with the help of the media and the geotag app’s daily participants,

We achieved a total of 7,123 notes, and using people's position on earth as virtual musical notes, we created a musical composition, which we then turned into an analogue music box, and for the first time on the 3rd of January of 2012 we where able to play for 3,000 visitors of the festival and all of Cartagena, the real Sound of the Americas.
