Each photo set is a different size. Therefore, each sound piece is a different length. The music loops each time it ends. Each loop shifts the position of any musical score relative to the others. This generates a mix of notes that continually changes. The pieces are harmonically locked by the composer, producing one long musical experience that plays forever without repeating. This is called a Perpetual Intermix. Familiar note sequences repeatedly arise, however, and they stick in the listener’s mind. When people leave the exhibition, they are often humming some melody only they have heard.
