English skills are essential as long as you work with a focus on overseas. The ability to check information on the Internet, the ability to communicate via email, and the ability to speak are also very important. As long as you are in the music business, you should communicate with both French and Asian people in English. But more important than that is communication skills. Do not hesitate, say what to say. If you can not hear what the other party is saying, listen in this word and check. Such an attitude is necessary.
