Notes/sketches begun 10 April 2006. This score begun 22 May 2006. Titled, finally, 23 May: the title, which sounds like "hinterland", is a play on words. "Inter" means between, among, in the midst of, within, as well as mutually and reciprocally. This piece explores the world between tonality and atonality, separately and simultaneously.
