My musical knowledge came the old fashioned way. I studied. Before my studies I drew my talent as a strategic planner from my successful business career to layout a path to produce a very fine quality musical product.
It was clear to me from the beginning that I would need to be competent in at least 4 areas of the music business to build a rewarding and profitable career/business. The first order of business was to learn how to write music, so I studied music theory with a college professor that was also an accomplished pianist, and woodwind artist playing with two symphony orchestras and a jazz ensemble.
