Music

Whether it be driving the frightened soldier toward his almost certain death,
Whether it be intertwining the love of the couple swaying to it,
Whether it be calming the tortured soul who has lost their self,
Whether it be playing in the teenager's room while they contemplate the future,

It has existed from the beginning of time
Coursing through our body and driving us to the very extremes we fear
Or encasing the memories of our most beloved people in it
It's a natural thing to hear it in the whisper of the grass as the wind howls its own song
To listen for the breathing of the precious soul as they sleep soundly

Its Music

Well, first I'd like to say welcome. I'm sort of new too but I still think that I maybe able to help you, if you need any. The people with green names are good with any help you need to go around.
The topic was nice, music. and so was your descriptions but sometimes I think you over describe. Poetry is usually word play on how effective you can be but certainly, it's your work, your call.
The whether it be sounds complex you could try reducing it to , whether it and use the present tense instead of the continuous. To MAKE THINGS SIMPLER.

Coursing through our body and driving us to the very extremes we fearsounds redundant and doesn't fall in the flow hereOr encasing the memories of our most beloved people in italso redundant

To listen for the breathing of the precious soul as they sleep soundly

The punctuation was good and grammar nearly flawless. Good luck. Hope my review helps.

I think the words in this are wonderful, as is the concept. Going with the 'rules' of poetry, your grammar and spelling is excellent. However, what I'm about to say next is purely suggestions. As always with reviews, take what you want and throw the rest away

If this were my poem (although it isn't, bear with me here) I would change a couple things:

Whether it be driving the frightened soldier toward his almost certain death,
Whether it be intertwining the love of the couple swaying to it,
Whether it be calming the tortured soul who has lost their self,
Whether it be playing in the teenager's room while they contemplate the future,

The 'whethers' are meant to be repetitive, I know, but they get a bit tiresome. Perhaps if there was only one 'whether' at the beginning, and you continue the same? Like so:

Whether it be
driving the frightened soldier toward his almost certain death,
intertwining the love of the couple swaying to it,
calming the tortured soul who has lost their self,
playing in the teenager's room while they contemplate the future,

Hmm... I don't know. Your choice.

Also, I really believe that some spacing would be nice for this. Instead of writing the whole phrase on one line, establish a rhythm.

It has existed
from the beginning of time
Coursing through our body
driving us to the very extremes
we fear
Or encasing the memories
of our most
beloved

Many different styles of poetry vary in their structure, but maybe you could ponder adding some more spaces?

Punctuation.
I'm not an expert, but you've been capitalizing the first letter of each line, whether it's necessary or not. I know, this is what we learned in school, but frankly, most English teachers aren't young writers
If your poem was a paragraph, would you put the punctuation in the same places? Commas, periods, ellipses all insert different types of pauses. Read it aloud if you need to, and figure out the effect you want.

Ah, sorry I'm not the best reviewer! If you need more advice, perhaps you could ask a friend on here, or request a review from the 'Will Review for Food'?

Hope I helped, even a tiny bit
