Louis Vierne (1870-1937) studied privately with César Franck and was appointed titulaire organist at Notre-Dame (Paris) in 1900. Numerous concert tours throughout Europe and the USA made him well-known outside France. His pupils included Marcel Dupré, whose pupil Thierry Escaich has worked on this edition. Vierne's organ works are masterpieces of organ music and are firm favourites in the virtuoso organ repertoire. In particular, Vierne raised the form of the organ symphony to a stylistic peak.
The famous collection of Pièces de Fantaisie, comprising 24 fantasy pieces in four volumes (Livres I-IV), has become internationally known. With their varying degrees of difficulty, the pieces are suitable for both professional organists as well as advanced pupils and students. The collection comprises mainly individual movements which are suitable for use on many different types of occasion. The Pièces en style libre pour orgue ou harmonium, comprising 24 pieces in two volumes, are shorter and technically easier. These are miniatures of a rather meditative character, equally suitable for organ teaching or concert use.
