Good. I liked how the endings of every two stanzas rhymed (ie hurt and concert). It was a great piece of work over all, albeit a bit depressing (to me)... I agree with the comment about italicizing (did I spell that right?) the last line for emphasis. Great analogies with the 'harmonies of aches' becoming a concert.
This was also good like the last one I read from you. There is one thing though I suggest, maybe you could place the last line in italics for emphasize, like it was said very subtly, it would add some more effect at least thats how I see it. But thats just my opinion and you can take it or leave it thats up to you.
