When I was young, I struggled to find scores I liked of modern works.  To this day, acquiring a full score like “Porgy and Bess” written in full is challenging.  Life is too short, I don’t care about the possible income of selling my scores at $19.00 a copy. If someone out there can benefit in any way by studying a score of mine, it is all worth it.  Murphy Music Press sells printed-out scores and parts of my pieces.
