Male mice song syntax depends on social contexts and influences female preferences.

Further we found that tests for differences in the distributions of transition types for different starting syllables across contexts were also highly significant (not random), including for the m syllable [T X 2 (obs.) = 5167.109, df = 684, p < 0.0001; Figure 9 and Appendix A in Supplementary Material]; pair-wise comparisons using Chi-squared tests for each pair of contexts showed strong statistical differences (Figure 9 and Appendix A in Supplementary Material: p < 0.0001).
