Mahler Symphony no. 9

The Symphony No. 9 by Gustav Mahler was written between 1908 and 1909, and was the last symphony completed by the composer. It is actually his tenth symphonic work, as Mahler gave no ordinal number (nor the title 'symphony') to his symphonic song-cycle Das Lied von der Erde. The symphony is in four movements and has an average performance time of one hour and a half.
