I believe it is precisely
this permanent coexistence of metaphysical message through physical means
that is the strength of music.
我认为这样说是很准确的：
通过物理方法令形而上学之讯息达到永久共存
便是音乐的力量所在.
主句是：I believe it is precisely. 我认为它是准确的.
告诉我们 it 是什么的宾语从句是：
this permanent coexistence of metaphysical message through physical means that is the strength of music.通过物理方法令形而上学之讯息达到永久共存便是音乐的力量所在.
在从句中：this permanent coexistence是主语
metaphysical message through physical means 是定语解释说明主语
is the strength of music 中的 is 是谓语the strength of music 是宾语
所以从句就是
这种共存是音乐的力量所在.而metaphysical message through physical means是告诉我们什么样的共存.
那句子拆分开来就变成3部分
I believe it is precisely.主句
this coexistence is the strength of music 谓语从句
coexistence of metaphysical message through physical means 解释coexistence的定语
