Become a fluent, effective English speaker and writer. As a musician, you will communicate in music, but you will also rely heavily on your ability to communicate words. Everything from rehearsals to teaching, to writing grant proposals, to negotiating, to promoting your musical interests relies on fluent English skills. Focus attention on learning to speak and write effectively. Study one or more foreign languages.
Musicians practice their art internationally.
You are likely to perform music with texts in foreign languages, and to work with musicians from all over the world. Significant musical scholarship and criticism are in foreign languages. If you seek advanced degrees in music, reading fluency in one or more foreign languages is often required. Since foreign languages are difficult for many people, you should begin acquiring knowledge and skills in at least one foreign language as early as possible. Consult with your music teacher about which languages are best for you.
