Charles-Marie Jean Albert Widor was a French organist, composer and teacher. Widor wrote music for a wide variety of instruments and ensembles (some of his songs for voice and piano are especially notable) and composed four operas and a ballet, but only his works for organ are played with any regularity today. These include: ten Organ Symphonies, three Symphonies for orchestra with organ, Suite Latine, Trois Nouvelles Pièces, and six arrangements of works by Bach under the title Bach's Memento (1925). The organ symphonies are his most significant contribution to the organ repertoire. It seems unusual to assign the term "symphony" to a work written for one instrument. However, Widor was at the forefront of a revival in French organ music, which had sunk to its nadir during the early nineteenth century. A prime mover in this revival was Aristide Cavaillé-Coll, who pioneered a new organ that was "symphonic" in style.
