If you really must, you may use that melody. But I'm really hesitant to let you use it. It's one of my favorites, and I know that you have absolutely no intention of calling it your own. What helps though, is to write a melody over uhhh something like an A major chord and then a d minor.

Second opinion. I love it. It is truly beautiful in its own way. I guess this is your sttyle. I cant criticise that. Its excellent in its own way. Its not what i would have done, no, but its good.
Thank God for some one now days who writes good music.. lol

Starts off beautifully i must say.. That melody is.. love i guess you could say. That was in the first few bars. You complicated the sense of love, romance and tragedy too much.. Too much change, leave it simple then about half way build up the tension to climax a sense of even a nature of sex or a kiss.. That feeling.. It is good tho.. very overexagerated tho.. you can do so much more with one melody without complicating it.

If i have your permission, may I use that melody from the opening bars for a romanza? I must say that melody is.. ahh pure melody, I will quote you and It will give thanks for the melody on the front page. I do not plan to make money off it. Well done ari. I love it.
