Unanswered Questions shares the solo flute from Ethers, but the sober, intimate character inferred by its intention - in other times, the piece would have been entitled Tombeau de Dominique Troncin - renders the presence of other instruments superfluous. In vain one might seek a reference to the work with a similar title by Charles Ives, and these questions remaining unanswered find a musical characterisation in the "modest, unfinished melodies" stemming from flute harmonics.
