James Decker had been an active music maker ever since performing with his mother on radio broadcasts while he was a child. Over the years, he continued his pursuit of music study and eventually developed into one of the most sought-after symphonic hornists in the country. Jim later worked in nearly every movie and recording studio from Washington DC to Los Angeles. After years as a university music professor, he achieved the completion of his method book and his design of the IVASI video system. The IVASI products were created to provide training for conductors through reviewing videos of themselves – facilitating personal critiques and improvement as never seen before. Jim passed away in 2013 and will be missed.
