<HTML>Pianist Karl Ulrich Schnabel Dies .c The Associated Press   DANBURY, Conn. (AP) - Pianist and music teacher Karl Ulrich Schnabel, the son of famed pianist Artur Schnabel, died Monday at his home, his daughter said. He was 92. Schnabel taught master classes in Europe, Asia and in North and South America. He began teaching at age 13, preparing students who wanted to study with his father. Schnabel's daughter, Ann Mottier, said her father encouraged students to achieve the fullest possible understanding of the music they played. Asked once to define beauty in music, Schnabel replied, ``proportion.'' Schnabel was born in Berlin in 1909 and began playing piano at age 5. He studied with Leonid Kreutzer at the State Academy of Music from 1922 to 1928, debuting in Berlin in 1926 and appearing with orchestras around the world. He was especially interested in music for one piano and two performers. The Schnabels left Germany when Adolf Hitler rose to power and became American citizens in 1944. In 1950, Karl Ulrich Schnabel's book, ``Modern Technique of the Pedal,'' was published. Dedicated to the revival of music for piano duo, he performed first with his father then, beginning in 1939, with his American wife, Helen Fogel. After her death in 1974, Schnabel formed a new duo with Canadian pianist Joan Rowland. No funeral services were planned, but tributes are planned at the Berlin Festival next month.
