Story summary.It's set on Mars, among Martians introduced in "Ylla".
We learn of impending human visitors - the second expedition after first failed one in "Ylla". But only indirectly, by implication.
Looks like across the Martian cities, people have been singing strange songs in a strange language - "women", "children", & "men". Without understanding, & unable to not sing these strange songs. Musicians are producing strange tunes that they don't understand. Is the whole world going crazy because of their telepathic senses?
