Наденька N, nah, I was just kidding. It's just that your message was a bit hard to understand. Here, let me fix this:
First of all, one does not use the word "tender", implying feelings. I'd rather use "gentle", "sweet" or something like that. But then again, maybe it's just me. Also, you don't need "the" at the beginning of your sentence.
Then, you want to use "you" instead of "your". Or else, you may say "I want to listen to your serenade". Not "your to play".
Then, secret, not seacret (whatever that is anyway). Then I'd say very difficult to me, not "for me".
The rest is pretty much alright.
