It was announced Monday that Philadelphia Orchestra music director Yannick Nézet-Séguin will visit residents of the Pennsylvania SPCA’s Erie Avenue headquarters Wednesday evening. Now the SPCA and orchestra say the playlist has been set that he and his partner have created for animals there.

The playlist he and Pierre Tourville curated will be played for the dogs and cats on an audio system at the SPCA — and your pet can hear it, too, on Apple Music.

Nézet-Séguin and Tourville have shared their lives with cats who make occasional appearances on their social media pages.

Some of the music on the playlist is not of the soothing kind. The big audio surprises in Mahler and Bruckner, for instance, are not something you’d want to spring on a cat. Chopin Nocturnes? Sure. The opening to Also sprach Zarathustra, the music used in 2001: A Space Odyssey? Probably not.

For the curators’ part, the pieces were chosen with a certain significance in mind.

“Yannick and Pierre created this playlist together based on music that reminds them of their own cats as well as their love for cats in general,” said orchestra spokesperson Alexa Vecchione. “For example, they included Parsifal, as one of the first cats they raised together was named Parsifal. It’s all music that they associate with cats.”

SPCA spokesperson Gillian Kocher said the music would be administered at the shelter with care, to be “played at a very calming volume, and all of our animals are closely monitored as are the rooms at all times.”

Additionally, she said, the music is turned off during the night when no one is there.
