Quatre pièces d'orgue pour la liturgie de la messe - I. Liturgie de la parole, Introit

Jacques Chailley (born March 1, 1910 – died October 15, 1999) was a renowned French composer, musicologist, and teacher. He studied at the Conservatoire de Paris, where he earned his degrees in composition and musicology. Chailley was heavily influenced by Gregorian chant and early music, which became prominent in his compositions and academic work. He was a professor of musicology at the École Normale Supérieure and made significant contributions to the study and promotion of early music.

As a composer, Chailley created a variety of works, including choral pieces, orchestral music, and chamber music. Some of his major compositions include "Légende pour orchestre", "Chant d'Amour", and "Hymne à la lumière". His work is known for its blend of traditional and modern styles, drawing on historical forms while incorporating innovative techniques.

Chailley also wrote several books on music theory and music history, helping to shape French musicology in the 20th century. His legacy includes both his compositions and his scholarly contributions to music.

Chailley wrote a number of works for organ among them Quatre pièces d'orgue pour la liturgie de la messe (which was unpublished). Tobias Broeker purchased most of the manuscripts of Chailley's music, and (with the blessing of the family) made the score of this work available. It is dedicated to Jean Langlais, and we hear the first movement: I. Liturgie de la parole, Introit.

The work starts with a dissonant flourish, but ends with some rather bluesy chords and in a solid G-major.
