8. A Ghost-Orchestra Plays ‘Accompaniments’ Above the Stage

Rows of red Radio City Musical Hall theater seats

Two stories above the stage are a piano, glockenspiel, and drum set that accompany most concerts at the venue but have never been touched by musicians. This ghost-orchestra is actually inadvertently operated by the venue’s organists, whose manipulation of the air currents inside the organ pipes in the ceiling also hit sweet spots on the instruments and cause them to produce sound as well.
