Heartbeats during a Rachmaninoff marathon: Yuja Wang, Yannick Nézet-Séguin, orchestra, and audience [synchrony]

From the YouTube page:

On January 28, 2023, pianist Yuja Wang joined The Philadelphia Orchestra and conductor Yannick Nézet-Séguin at Carnegie Hall for a once-in-a-lifetime, all-Rachmaninoff marathon that featured the composer’s four piano concertos plus his “Rhapsody on a Theme of Paganini.” Throughout the performance, Wang—along with Nézet-Séguin, members of the orchestra, and concertgoers in attendance—wore devices to track their heartbeats.

Unprecedented and insanely demanding, Wang made history. These five pieces include two-and-a-half hours of music, 621 pages of score, and more than 97,000 piano notes.

Heartbeat plots, with commentary, start at about 3:15. Interesting observations throughout.
