Weingartner thought of himself as a composer just as much as a conductor. However, it is as a conductor that he is remembered today. His compositions are hardly ever played now. He composed in a late-Romantic style, and he was an influence on the composer Erich Korngold. He is best remembered today as one of the great conductors of classical music, who conducted in a precise way without exaggerated effects. He wrote books about music including one about conducting.
