I assume you can train dogs to howl on cue. So the stage would be filled with the best howlers who would be given mics going to an autotune audio system.
The orchestra leader would raise that stick thing and give the message to start howling and the perfectly tuned, beautiful peace would begin.
Not
sure of a barking session would be doable, they'd have to be quantized and the autocorrected barks would have to be much louder than the actual barks.
Had a record when I was a kid "Beatles Barkers" where they had howling dogs sing the Beatles hits. That was pre autocorrect so somebody put a lot of work into that. Loved that album.
Anyway, singing dog chorus, I'd pay to see that.
