History
The term Third Stream was coined by Gunther Schuller in 1957, after he began describing a respectful merging of jazz and classical music rather than a simple decoration of one style with the other. Schuller later explained that improvisation had to remain central if the music was truly to belong to this new “third” current. (arts.gov) In practice, the style took shape through composers and ensembles working across formal composition and jazz language, especially around the Modern Jazz Quartet and related projects. The idea never settled into a single sound; instead, it became a broad umbrella for works that try to keep the discipline of the concert hall and the living pulse of jazz in the same frame.
