About the third year of high school, An Tian Guangtian first appeared in the music industry. When he was in high school, he was attracted by the background music in the movies Railway Man and blade runner and the works of Henry Mancini, which greatly aroused his enthusiasm. He hopes to be an excellent composer one day and create film music as good as theirs.
After graduating from high school, he moved to Tokyo alone and started his career. In order to make up for his lack of knowledge of music theory, he entered a short-term music university in Tokyo and majored in composition and arrangement. During his short two years in college, he worked and studied day and night, working harder than ever before. Most of the teachers in short universities are part-time, and they have their own music career. Therefore, Guangtian will often follow these teachers around with their musical instruments and heavy equipment, but at the same time, they have learned a lot of valuable things by carefully observing the work of teachers. But it is often ridiculed by teachers. In the second year of short-term study, Guangtian worked as an intern under a teacher in the music department of a big-name game software company. One day, the teacher suddenly asked him about his plan to apply for a job. The teacher recommended him the position of game music designer of Square (renamed SquareEnix). At first, Hirota didn't intend to write game music, but he decided to give it a try, so he submitted his resume, three audition tracks and a special recommendation letter from the teacher. After receiving the reply, Hirota wrote three more songs and sent them, and was then asked to attend an interview.
