Sigfrid Karg-Elert was a German composer of considerable fame in the early twentieth century, best known for his compositions for organ and harmonium. His musical style can be characterized as being late-romantic with impressionistic and expressionistic tendencies. His profound knowledge of music theory allowed him to stretch the limits of traditional harmony without losing tonal coherence. The 30 Caprices for Flute were written specifically for a friend of Karg-Elert's, a flautist bound for service in the war. These short exercises were designed to challenge linear one-staff thinking and in short, keep the friend from becoming bored. They are now a standard set of technical, dynamic, and phrasing exercises for young flute students all over the world.
