Vivaldi and Bach mainly. Elgar’s Cello Concerto in C Minor seems to be a favourite right now. They like Delius in the right mood, but unfortunately I do not.
Their favourite is Jaap Ter Linden’s recording of Bach’s Cello Suites, I think because it’s a little richer sounding than Yo-Yo Ma.
I read somewhere that dogs love cello music because it has the same tones as the human voice, and it certainly seems to calm them more than any other music.
I wanted to start some music playing via Sonos in another room for my dogs earlier while I was on a call.
It took nearly two minutes for the app to update and be able to select my "calming cello music for dogs" playlist.
