Khbreit - I think I can recommend you to take a look at the abc notation and use some freeware utility like abc2midi to turn it into some thing you can listen to. The only knowledge it requires is to identify the tone (i.e. its "name") from the key you hit (e.g. on a piano) or from the note you see on a piece of sheet music. This may be a little euphemistic as there are still other aspects of music, but still - IMHO that's the most advanced opportunity to communicate music to and from listening. Works in both directions, really.
I am especially interested in the tune you are using because when I read those lyrics some special KIND of tune comes to my mind (with many variations possible but it would remain the same kind) and I wonder from what song (songs?) I know it, and I also wonder whether you are thinking of the same.
