In this year when the G. Henle Verlag celebrates its 50th anniversary, I would like to congratulate from the bottom of my heart everybody who works or has worked for this wonderful publishing company and to express my gratitude for everything they have done and continue to do. I'm convinced that many musicians will join me in saying how useful and valuable your work is. May the G. Henle Verlag prosper continuously - for the benefit and joy of so many musicians and music lovers!
