Daniel Felsenfeld, who is a composer of classical music and a writer explain the process of his identity changes in the passage, “Rebel Music”. He was at first very distance from music especially classics. However, at the age of 17, he fall in love with the music which is a rebellion music for his age. It was not rock, hip hop, metal or punk. He realizes that he is not the only person when he found out that there were composers who are studying classical music just like him. Reading his passage, the process of writing music seems to be quite familiar with writing in general. It needs practice, identity of what we are writing, introduction, and how it was made for the audience. It makes me realize how writing is very essential for everyone regardless of becoming a writer or not. Every career requires writing as an educational skill and it makes every do better.
