Mahler wrote to his friend Willem Mengelberg that his Eighth Symphony was his greatest work ever. ‘All the other symphonies were anticipating this.’ Moreover, he experienced it as if the piece of music was dictated to him in a vision. In two monumental movements, Mahler says he sings of the entire universe. ‘There are no longer human voices sounding. They are planets and suns, revolving in their orbits.’ Practically speaking, it is also a rather voluminous work. Mahler did often need very many performers, and in this Mahler’s ‘symphony of a thousand’, there are close to four hundred. Or more: in 1912, Mengelberg conducted a version with two thousand musicians and singers. (source: concertgebouw.nl)
