Description : How does one train to become a music conductor and how much do they earn?

Last Answer : answer:Firstly, one must understand that conductors of orchestras are kind of like the rock stars of the classical music world. It's not impossible to become one, but it is a long hard road that ... , BTW, is essentially why I decided to drop the music major and opt for software engineering instead)
