What is symphonic jazz?

Symphonic jazz is a genre of music that fuses elements of jazz and classical music. It typically involves the use of a jazz orchestra or big band, as well as classical instruments such as strings, woodwinds, and brass. The music often features complex arrangements and improvisational solos, and it can range from light and swinging to dark and brooding. Some notable examples of symphonic jazz include Duke Ellington's "Black, Brown and Beige," Gil Evans' "Porgy and Bess," and Maria Schneider's "Concert in the Garden."
