Trois Pieces pour Orgue ou Harmonium

Juliette Nadia Boulanger 1887 – 1979 was a French composer, conductor, and teacher who taught many of the leading composers and musicians of the 20th century. She also performed as a pianist and organist. From a musical family, she achieved early honours as a student at the Paris Conservatoire but, believing that she had no particular talent as a composer, she gave up writing music and became a teacher. In that capacity, she influenced generations of young composers, especially those from the United States and other English-speaking countries. Among her students were those who became leading composers, soloists, and conductors, including Aaron Copland, John Eliot Gardiner, Dinu Lipatti, Igor Markevitch, Philip Glass, and Ástor Piazzolla.

Although she was a well known organist, she only left a few works for the organ. The Trois Pieces pour Orgue ou Harmonium were written in 1911 and consists of three parts:
1. Prélude
2. Petit canon
3. Improvisation
