Open Goldberg Variations

The Open Goldberg Variations is a non-profit project that created a high quality studio recording and typeset score of Johann Sebastian Bach’s Goldberg Variations, and placed them directly into the public domain. By releasing an entirely free version of the classical masterpiece, the project aims to change a common problem: in theory, classical music is a common property due to advanced age, yet it is hard to find quality recordings of it online due to copyrighted restrictions on the performances. Open Goldberg Variations cemented a free, quality version into the public domain, making the music available for everyone and everything, including schools, universities, musicians, private persons and even commercial productions.
