St Bavo church Haarlem the Netherlands The organ of the Sint-Bavo church (the Christiaan Müller organ) is one of the world's most historically important organs. It was built by the Amsterdam organ builder Christian Müller, with stucco decorations by the Amsterdam artist Jan van Logteren, between 1735 and 1738. Upon completion it was the largest organ in the world with 60 voices and 32-feet pedal-towers. In Moby-Dick (1851), Herman Melville describes the inside of a whale's mouth: "Seeing all these colonnades of bone so methodically ranged about, would you not think you were inside of the great Haarlem organ, and gazing upon its thousand pipes?" Many famous musicians played this organ, including Mendelssohn, Händel and the 10-year old Mozart, who played it in 1766. The organ was modified a number of times in the 19th and 20th century and most drastically altered in the renovation by Marcussen between 1959 and 1961. Further voicing work was undertaken between 1987 and 2000. Today concerts are regularly held in the church, and all through the year special opening times are organized so the public can walk in free of charge to listen to this famous organ in action. A local story goes to say that the bass of the organ was so low, the mortar in between the brimstones started to brittle to nothing. (from wiki) thanks for viewing & comments
