Help understanding how these clauses fit together


The taiko memoir saga continues.

Today's challenge:

> それを癒せるのも、自分自身や、その一人一人を包む鼓童の奏でる音からでしかないのだが・・・

Here's the context leading up to (and including) this sentence, which is the
last one on the page:

>
> 体力に頼るところのおおきい鼓童の太鼓は、個々人の体調の良・不良に大きく左右される。それにより舞台の出来・不出来も生じる。長い時を掛けて得られていた信頼や、ほどけかけていた誤解、新たな邂逅などまで、総て崩れ落ちてしまう危険性がこんなところにある。それは、対お客様との関係であり、また、個対メンバーとの関係でもある。一つの小さな病いが、別の大病を招いたりする。それを癒せるのも、自分自身や、その一人一人を包む鼓童の奏でる音からでしかないのだが・・・

My understanding is that he is discussing the vulnerability of a group based
on the performance of its parts: The odaiko (large drum), despite being an
instrument of great power, is at the mercy of the person playing it. Success
or failure of a stage performance overall is contingent upon each individual
performer in the same way. Trust takes a long time to earn, but can be
unraveled by a simple misunderstanding, and this balance put the group in
danger of coming apart until another opportunity presents itself. A small
weakness begets a greater disease...

...Then we arrive at the final sentence, where he talks about the cure for
this "disease" (I think?) and I'm not exactly sure how all of those clauses
interact with one another. My best guess is: _It's a disease that can only be
cured when oneself and each of those individuals envelop themselves in the
sound of Kodo's music._

Or something like that. :) Thank you for your help!




Let's start from this sentence:

> 音はそれを癒やせる。  
>  The sound can cure it (=病).

Using the pattern sometimes referred to as [cleft
construction](https://japanese.stackexchange.com/a/19208/5010):

> それを癒やせるのは音だ。  
>  It's the sound that can cure it.

～でしかない means "nothing but", "only". も can be used instead of は to express the
stronger negation (See [def.
3㋑](http://dictionary.goo.ne.jp/jn/218351/meaning/m0u/%E3%82%82/)).

> それを癒やせるのも音でしかない。  
>  It's only the sound that can cure it.

This から seems to mean によって ('by', 'with', 'using'), but I find it a bit
strange because we don't usually say "薬から病気を癒やす". But anyway...

> それを癒やせるのも音からでしかない。  
>  It's only by the sound that it can be cured.

音 is modified by the relative clause "自分自身や、その一人一人を包む鼓童の奏でる":

> それを癒せるのも、{自分自身や、(その一人一人を包む→)鼓童の奏でる→}音からでしかない。  
>  It's only by the sound played by oneself or surrounding Kodo that it can be
> cured.

And you're parsing the following sentence wrong.

> {(a)長い時を掛けて得られていた信頼や、(b)ほどけかけていた誤解、(c)新たな邂逅などまで、}総て崩れ落ちてしまう危険性がこんなところにある。

Literally: {From (a) trust which took long time to earn, to (b)
misunderstandings which have almost unraveled, and to (c) new encounters}; a
danger lies here that all of them (=(a)-(c)) come apart.
