Kafka was almost right! or, Mus Musicus

Time held me green and dying,
Though I sang in my chains like a mouse.

Kafka wrote of Josephine, the mouse singer. It now appears that mice do sing. Only it is the boy mouse and not the girl who raises his shrill trill in joy. It is too shrill for us to hear . . .

Ultrasonic Songs of Male Mice

Previously it was shown that male mice, when they encounter female mice or their pheromones, emit ultrasonic vocalizations with frequencies ranging over 30–110 kHz. Here, we show that these vocalizations have the characteristics of song, consisting of several different syllable types, whose temporal sequencing includes the utterance of repeated phrases. Individual males produce songs with characteristic syllabic and temporal structure. This study provides a quantitative initial description of male mouse songs, and opens the possibility of studying song production and perception in an established genetic model organism.
