If you're asking about how to do "poetry", then, I don't know. But, if you're talking about how to put a melody on a paper, I can help.
First: when you have some notes on your mind, don't let it gone. Whistle, or play this on your instrument.
Second: If you're playing this in a instrument, write the notes and after, the time between notes.
Obs. sometime happen's to me dream with a sequence of notes while i'm sleep and when I wake up, i don't remember. But once time I've get and put on paper one of those melodies :-)
