The entire poem has meaning from start to finish. It is about finding that "someone" -- you want more at the beginning, and you realize later you want something different to better suit you then you find what you are looking for and want it to last forever. At the beginning the destination for this person is unclear and it continues that way until the end where they use there knowledge from past, present, and future as a guild to keep there dream alive. The music creates anger at first when they are happy with the end result, it then creates confusing when they are unsure of the difference they long for and at the end they find joy when the path that "music" has taken them on leads to their hopes and dreams becmoming a reality.
