Milky Ways lasts about 21 minutes and is cast in three movements:
- The Infant Gaze
- Interplays
- At the Fountainhead of God
The title of the work refers both to the eponymous galaxy containing the Solar System, but also the act of nursing a baby, from which the piece draws its theme. The title of the first movement "The Infant Gaze" refers to a new-born child looking at the mother, while the finale "At the Fountainhead of God" refers to the milk flowing from mother to child.[1]
During the composition process, Tarkiainen learned of the early death of Nicholas Daniel's mother Billie when the oboist was a young man. In the score program note, she wrote, "The concerto accordingly ends with a moving farewell scene polarising the two counterparts birth and death, the two sacred moments in life." To this effect, the composer included a moment of blocking during which the solo performer rises, walks behind the orchestra, and exits through the stage door, all the while being followed by a spotlight.[1]
The work is scored for solo cor anglais and an orchestra comprising two oboes, three clarinets (3rd doubling bass clarinet), two bassoons (2nd doubling contrabassoon), four horns, two trumpets, two trombones, tuba, timpani, three percussionists, harp, piano (doubling celesta), and strings. The score also requires the use of a spotlight in the concert hall.[1]
