Édouard Batiste was a French composer and organist born in Paris on 28 March 1820, and studied at the Imperial Conservatoire as a teenager, winning prizes in solfège, harmony and accompaniment, counterpoint and fugue, and organ.
In 1842, he became the organist at Saint-Nicolas-des-Champs church in Paris, where he remained for 12 years, before becoming organist at Saint-Eustache Church. While at Saint-Eustache, he performed the organ in the premiere of Hector Berlioz's Te Deum in April 1855, conducted by the composer. He died in Paris on 9 November 1876.
Joseph G Lennon,one of his students from America said.
'Batiste's organ playing was one of the chief attractions for foreign musicians visiting Paris. Basite would play from memory Bach, Mendelssohn and music from German composers. His improvisiatins were also very memorable.'
This Larghetto has a funerial feel to it and I have played it on the Lipiny sample as that fine instrument is not often heard. I have used the Trumpet with it's French accordion feel.
Here is some liturgical music by Batiste;
