During courtship, Drosophila melanogaster males sing to females a song composed of rhythmic pulses and sine song. In this issue of Developmental Cell, Shirangi et al. (2016) show that a cluster of doublesex-expressing neurons directs the production of the sine song component through functional linkages to wing motoneurons.
