Third stream
![Gunther Schuller conducting][float-right]Third stream is a musical genre that synthesizes the improvisational and rhythmic qualities of jazz with the compositional forms and harmonic sophistication of classical music.[1] The term was coined by composer and conductor Gunther Schuller in a 1957 lecture at Brandeis University, where he advocated for a "third stream" arising from the convergence of these two primary musical traditions.[2] This fusion sought to transcend the boundaries separating jazz and classical performers, fostering collaborations that preserved the integrity of both while creating novel expressions, as exemplified in works involving the Modern Jazz Quartet and compositions by Schuller himself.[3] Though met with criticism from purists who viewed the blending as diluting each genre's essence, third stream paved the way for later experimental hybrids and demonstrated the potential for mutual enrichment between vernacular and art music traditions.[4]
