"Third stream" refers to a concept in music that blends elements of classical music with jazz. This genre emerged in the mid-20th century, aiming to create a new style that incorporates improvisation and complex harmonies, drawing from both traditions. Notable figures in this movement include composer Gunther Schuller, who coined the term in 1957. The idea of third stream extends beyond music, influencing various art forms and educational practices. It encourages collaboration between different disciplines, fostering innovation and creativity. This approach can be seen in programs at institutions like Berklee College of Music, where students explore the intersections of diverse musical styles.
