<p>If your desire is to be a college professor in the field of music, your work is cut out for you! You must either be an almost peerless performer on your instrument or voice, or you must be a scholar in the fields of music history, music theory, music therapy, music education, holding a Ph.D. Most college professors began their careers in smaller regional schools, teaching a variety of things, their instrument and music history, voice and opera, etc. Only the premiere performers can achieve a position at the major music schools and schools in the metropolitan areas. Being a high school teacher is a different process, but you must still be proficient in a performance area. If you are not very gifted vocally, or you have not seriously studied a musical instrument, it will be very difficult for you to pursue this idea. Good luck.</p>
