Lili Boulanger was born in Paris in August 1893 into a household where music was the family trade. Her father, Ernest Boulanger, was a composer who taught singing at the Paris Conservatoire; her mother, Raïssa, was a Russian singer; her older sister Nadia would become one of the most influential composition teachers of the twentieth century. Lili was the second daughter and the ill one. A childhood illness left her permanently vulnerable, and the pattern of her life was set early: intense work in short bursts, interrupted by collapses.
That fragility kept her out of a normal Conservatoire education. She studied composition privately with Georges Caussade instead, and in January 1912 was admitted to Paul Vidal's composition class. She entered the Prix de Rome that year and did not finish the competition; her health gave out mid-way. She entered again in 1913 and won it outright with the cantata Faust et Hélène, at nineteen, the first woman to take the prize in its history.
What is usually said about that win is that it was a barrier broken, and it was. What is said less often is how narrow the opening turned out to be. The prize came with a stay at the Villa Medici in Rome, which the war then interrupted, and with the expectation of a long public career, which she did not live to have.
She wrote a great deal in the five years left to her, and the work is not the polite salon music the biography might suggest. The psalm settings in particular — Du fond de l'abîme above all — are dark, harmonically severe pieces written by someone with no interest in being charming. During the war she and Nadia organised support for musicians serving at the front. She was working on an opera, La Princesse Maleine, after Maeterlinck, when she died at Mézy-sur-Seine in March 1918. She was twenty-four. Her last piece, a Pie Jesu, was dictated because she no longer had the strength to write it down herself.
Her sister outlived her by sixty-one years. Nadia had placed second in the Prix de Rome in 1908, stopped composing in her thirties, and taught instead — Copland, Piazzolla, Quincy Jones and a long list of others. She programmed and championed Lili's music for the rest of her life, which is a large part of the reason any of it survived to be recorded.
