It is important to be noted that Mahler work is never conducted. The Mahler is an exceptional feat of the imagined and put to paper, it should be remembered that Mahler has always revised its scores after the performance. The Mahler has always clarified its intention in relation to the clarification of the textures. In the later versions, there are nuances that are explained and modification of the tempo. It is sparsely marked in comparing the scores of the 9th with that of the 7th or 6th.
It often happens with the conductor of Mahler, that he gets stuck in one main temp per movement. The temp has been illustrated as the objective and changing frequently the tempi as subjective.
This opens up the debate between the far ranging misconception and confusion regarding subjective and objective interpretation of Mahler.
There have been a number of instances where the conductor related to the performance of the Mahler has been stuck to one tempo per movement. This can be termed as the objective and the one who has been changing frequently the tempi as subjective.
It is more technically demanding the 2nd movement of the 9th Symphony. It can be said that for the listener too, the 2nd movement is more demanding. The first movement when performed by a performer is about 30 minutes long that is demanding of concentration from a listener, but the Mahler ensures the persuasiveness of the listener in seamless way and placing perfectly the cinematic sense. The 2nd movement, however, has demanding much more from the audience with more irony and starting upsetting one’s expectation as it progresses.
