Universität Mozarteum Salzburg, also known simply as Mozarteum Salzburg, is a university in Salzburg, Austria which specializes in music and the dramatic arts. It is famous as one of the most respected universities in Europe for music studies and was named after Salzburg native Wolfgang Amadeus Mozart.
The predecessor of the Mozarteum Orchestra of Salzburg was the "Cathedral Music Association and Mozarteum", founded in 1841 through the energies of Mozart's widow Constanze Weber Mozart. Its purpose was the "refinement of musical taste with regard to sacred music as well as concerts".
The original 100-rank grand concert hall organ was built by the Austrian firm Rieger in 1914. A completely new organ in neo-baroque style was installed in 1970 by E.F.Walcker & Cie. This organ was dismantled in 2008. In 2010 a new 50 stop tracker action organ was installed by Hermann Eule Orgelbau, Bautzen.
The pipe organ in the small concert hall "Wienersaal", invisibly located in an organ chamber above the stage, was built in 1914 by Rieger with 25 stops and electro-pneumatic action. It was rebuilt in 1941, including a new console and some neobaroque modifications. The organ is in bad condition, but still playable.
