This year's lecturer is Daniel Barenboim, who has become known as one of the most versatile pianists of his generation. His skill as a conductor and a musician has led him to world recognition and the appointment as Chief Conductor for Life by the Staatskapelle Berlin. He has also won a Grammy for his recording of Wagner's Tannhäuser and received the Wilhelm Furtwängler Prize for his work with the Staatskapelle Berlin. In his final lecture, delivered in Jerusalem's International YMCA, Daniel Barenboim discusses the power music has beyond words. Music is more than just a physical power it is also has an emotional strength. He explores the hold music has over us and the association that music can evoke. He distinguishes between the substance of music and our perceptions of it.
