How does Thomas Mann use imagery in The Magic Mountain?

Imagery:

"Music...there is something only semi-articulate about it, something dubious, irresponsible, indifferent. ... Music, it would appear, is movement for its own sake—although I suspect it of quietism. Let me overstate my case: my distaste for music is political."

"Death is to be honored as the cradle of life, the womb of renewal. Once separated from life, it becomes grotesque, a wraith—or even worse. For as an independent spiritual power, death is a very depraved force, whose wicked attractions are very strong and without doubt can cause the most abominable confusion of the human mind."
