I agree that music is essential in life. I like the way you associated music with celebration. It is absolutely true, you sing the birthday song to celebrate another year of life. When celebrating the end of life on earth, you also hear music, it is more somber, but nonetheless, still music. 

I view music as a form of poetry. I think music should also be preserved, lately I feel like the art of music is not as respected. Of course, here in Austin, it is more respected, but Austin stands alone when it comes to love of music. 

Did Dufay also put his compositions on paper himself, or did he have scribes?
