Before her early death, Lili Boulanger wrote a number of notable works not yet fully influenced by the harmonic explorations being developed by her older sister. Lili’s final completed work, Pie Jesu, was dictated to Nadia and published in 1922 as a work for small chamber ensemble, although a scaled-down version for voice and organ had also been prepared. She was 16 years old when she first made sketches of Pie Jesu, probably as part of an uncompleted requiem mass.
