Very interesting. I think you have something to work with here. After reading the first time, I'm left with an impression of someone taking advantage of an innocent? I'm not sure If I'm reading into this too much. My understanding would increase dramatically if you answered who is "they"?

Also, I can tell you've cut-n-pasted. I fell you would benifit greatly by utilizing stanzas to designate between thoughts or emotions. For example:

Rendered me unattuned
to sweeter notes;
Faithful to their minors.

Poison travels down
the finger tips,
staining like blood,
buried, bloody keys,

Above's an example with an attempt not to change what you've written. This may read entirely different if you didn't cut-n-paste. If so, forgive me and ignore me.

I don't know if you intended to be oplaque or if I'm just a ninny; however, if you wish to be direct with your readers, I'd rewrite, adding descriptive details.

Great start. Write on.
