 In September, 1855 Liszt wrote of his intention to send the score of his "Psalm 13" to Berlin so that Conradi could make a fair copy for the first performance there.The extent of Conradi's help with Liszt's early orchestration has been well documented by Liszt scholar Peter Raabe, who demonstrated that, whatever the position regarding initial drafts, the final versions were always Liszt's own.Conradi wrote eight operas, a ballet, five symphonies, overtures, and string quartets as well as dance music, songs, vaudeville sketches, farces and potpourris (which were performed in garden concerts for many years).
