The Sound Cloud takes reference from Arvo Pärt’s music as well as the dense pine forest. Its shape is derived from the song “Spiegel im Spiegel”, consolidating the main sequence spectrogram of the song into the curves of a roof. This cloud of sound forms an introverted space within where the music is played and listened to and a space underneath that becomes the work and meeting place for the people interested in the legacy of the composer. The cloud only touches the ground where it is thickened to house the performance space, and otherwise hovers between the trees, like the tree house of the observation platform, suspended in the natural environment of the forest. The complex rooms of the program are organized in their functional groups and combined into a box building that is placed underneath the roof. Underneath the roof and in the center of the overall courtyard shape a poetic space is created within nature, where the memory of Arvo Pärt can reside.
