Non troppo lento (Au pied de l'Autel, Book 2, No. 23)

Joseph Guy Marie Ropartz (15 June 1864 – 22 November 1955) was a French composer and conductor. His compositions included five symphonies, three violin sonatas, cello sonatas, six string quartets, a piano trio and string trio, stage works, a number of choral works and at least 15 organ pieces, often alluding to his Breton heritage.

This piece is from Au pied de l'autel, 100 pieces for harmonium composed in 1916-19 and dedicated to A. Dupont.

Ropartz was born in Guingamp, Côtes-d'Armor, Brittany. He studied initially at Rennes. In 1885 he entered the Conservatoire de Paris, studying under Théodore Dubois, then Jules Massenet, where he became a close friend of the young Georges Enesco. He later studied the organ under César Franck.
