Sound Postings

The Sound Postings team manages Yo-Yo Ma’s performances, recordings, and public engagement and collaborates with partners around the world to develop and produce cultural projects that advocate for a world guided by humanity, trust, and understanding. 

Beginning in 2018, Sound Postings produced the Bach Project, a 36-community, six-continent tour of Bach’s cello suites paired with local programming which explored culture’s role in imagining and building a better world. From 2021, it produced Our Common Nature, a cultural journey made up of live events, new commissions, and digital storytelling which celebrated the ways that nature can reunite us in pursuit of a shared future.
