Mahler's cantata Das klagende Lied continues to be a rarity on concert programmes, despite the fact that the composer is recognised today as one of music history's most preeminent figures, many of whose works form part of the standard repertoire. The significance of this large-scale symphonic choral piece is that it represents the foundation of Mahler’s more widely-known compositions. As such, it is a key component in understanding Mahler and interpreting his works. It could be said that Das klagende Lied represents a summary of all Mahler's creative output up to that point in his life. It also foreshadows the works that were to come.
