O Lune is the result of two shorter pieces I wrote then revisited. The first I wrote as a class assignment on my own poem; the second as an exercise in choral writing I put together on the same words for a Vancouver Chamber Choir workshop. When I later revisited the pieces, I felt a strong link between the two, and that the multiple voices and shimmering harmonies of the second piece seemed to directly respond to, or echo the soprano's call in what has become the first movement.
