She wrote about Richard Haley's Concerto of Deliverance, which, as he was heard playing it in his house in Galt's Gulch, appears to be a solo piano piece. A concerto is, by definition, accompanied.

I'd like to say that she left it out in a case of poor artistic judgment, but to be honest, I have no idea.

Of course, she indeed knew very little about science. Galt's Amazing Laws-of-Physics defying motor attests to that.
