The triad of great classical music geniuses (Bach, Beethoven and Brahms) was proposed by Hans von Bülow in the 19th century. Although there was debate about who should be the third member of a pinnacle in which no one disputed the presence of Bach and Beethoven anymore, Von Bülow passionately defended Brahms based on the tonality of Beethoven's third symphony: “My creed is E flat major, the tonality of the «Eroica», with its three flats in the key (3 b): Bach-Beethoven-Brahms.”
