 We have now some music by a 19th century German composer who was a very prolific composer, also very proficient at the piano, the violin. He was a great conductor. He conducted the Leipzig Gewandhaus Orchestra for many, many years, a great teacher. And yet we don't hear from him very much. Karl Reinicke is his name. This is probably his best-known composition. It's a flute and piano sonata called Undine, which refers to the water sprite sound.
