In France, the organ builder Aristide Cavaillé-Coll (1811-1899) was a real genius. His organs had lots of new ideas including the Barker lever (which made it easier to play on coupled manuals) and placing families of stops on to separate chests. Organists could change their registrations quickly, pushing in or pulling out the stops that they needed. Composers included César Franck (1822-1890), Charles-Marie Widor (1845-1937) and Louis Vierne (1870-1937). The last two wrote long works in several movements which they called Symphonies because they were full of colourful sounds like those in a symphony orchestra. There were usually three manuals called "Grand", "Positif" and "Récit" placed in that order (with Grand nearest to the player). The Grand had warm foundation stops and big reeds (it was like combining the classical plein jeux and grand jeux). The Positif had string stops as well as a solo reed, and the Récit had lighter reeds.
