Sound Postings

Sound Postings is Yo-Yo Ma’s creative team, collaborating with a wide range of partners to manage Yo-Yo’s professional and philanthropic activities and to create, develop, and produce artistic projects that advocate for a world guided by humanity, trust, and understanding. 

From 2018 until 2023, Sound Postings led the production of the Bach Project, a 36-community, six-continent tour of Bach’s cello suites paired with local programming exploring culture’s role in imagining and building a better world. Most recently, Sound Postings has partnered with Yo-Yo to conceive and produce Our Common Nature, a cultural journey to celebrate the ways that nature can reunite us in pursuit of a shared future.
