Hi. I see this list of songs you are working on, and it looks quite interesting. I see potential for a theme for each major world biome as well, but I do have some questions out of natural curiosity. Not sure which of those tracks would, for instance, go well with the withering heat of a desert, or the intense rain or humidity of a tropical jungle or rainforest, or the electronic/technical beat found in a few largish rpg cities.
Also, if I were looking for rpg music (which I might be), I'd say each of these bulleted "themes" should probably have at least two variants, maybe even three; a variation could be given aural presence by factors like increased tempo from a previous variant, or by increased volume from one or more instruments, or by "more intense" instrumentation. I think it's good to add variety to each theme, because as a party continues on their journey, the musical background in certain locations can get either more intense or less intense, depending upon many factors. (Don't get me wrong, finish each primary theme as you go along; but then come back and make one or more "tweaked" versions of the theme.)
Finally. Will your license allow me to also use the finished tracks in my own rpg-maker-like engine/project too?
