Like a friendship, although the overall feelings of liking and affection does not change for the other person, the intensity and definition of that love you have for that person changes, from "just friends" love (agape) to "just for a life time.." love.. yeeah I like talking about themes of music :)
Ah hah! I am very glad you mentioned that.. ;) There is a central melody hidden within the motions, and around the last few measures it becomes more prominent, and evolves into the love once started as a simple friendship. The "friendship" is the middle, with the random rhythm addition, but every 16 bars the melody changes, though it doesn't sound like it.
I love all the sounds in here but it seems like there isnt much of a central melody or it just isnt loud enough for the middle section. but in the begginning and end its very beautifull!!!
