Hey don't be so mean Krystof01 (although, it was quite funny in a cruel way) remember... different languages.. not everyone speaks english fluently (and I have been drinking)
Istyle, I'm not really sure. Writing melody revolves around so many things. It could be a solo melody, or a melody that goes over top of a chord progression. I'm sure there is a relation there, but why think about it? How can you come up with a 3 variable formula?
I don't think it's possible to explain to anyone *how* to write a melody. Anyone can write a 'melody', whether it's a 'pleasing' melody is cultural dependent, per-person dependent and a dozen other reasons. I find microtonal music somewhat annoying. The odd time I hear something that is acceptable, but most of it is just.. grating. East Indian music for example, it all sounds the same to me, but to people who appreciate it, I'm sure it ROCKS! Rap all sounds the same to me, but again.. someone likes it!
Maybe #3 is microtonal. But I doubt it. Intervalic, maybe.
I prefer dissonance. Constructive dissonance rocks.
A sine wave could be considered a melody(to someone, an alien perhaps). I don't know.
BTW, a good example of a song with 0 melody is Maria Carrie(sp? who cares) I can't for the life of me, figure out what is the point of that song. Wish I could remember the name of it... it's really bad, no melody, no background chord progressions..... WILD! Someone appreciates it though I'm sure.
