Usage: Like other scented signs, Arpege bypasses thinking centers of our brain and "speaks" directly to emotions through the limbic system. Combining rose, jasmine, orange blossom, and ca. 60 natural oils and extracts, Arpege is a classic consumer product for the nose. The name, derived from the Italian word, arpeggio (a musical term for playing the tones of a chord in quick succession rather than simultaneously), reflects the perfume's stratigraphic "layers" of smell.
