An American composer, he wrote this for himself and his flutist wife.  The four movements display the virtuosic abilities of the flute and the gentle, but sometimes raucous side of the tuba.  Each movement is titled after memories from the composer's childhood.  Tylopilus is reminiscent of a stroll through the woods.  The peaceful flute melody portrays innocence, while the ending signifies the difficulties that come with age.   Taris ponders the morality of good vs evil, with good finally winning out.  Traverse could be subtitled A Night on the Town.  It is about the bond, not just between the flute and the tuba, but between the performers themselves.  Tartarus, again, is about the difficulties that we encounter throughout life and, ultimately, the paths that lead us to who we are today
