Faire sings along with music — sort of sing-songy squeals, but she will hit the same note you are singing and sometimes grin as if she knows she got it right. Seriously! If I sing one note for her she will squeal along with me, then I adjust to a higher or lower note she will adjust her tone up or down too.
She dances too. If I put on a CD she usually only dance to the first track or so, then seems to tune it out, but radio jingles, buskers in the subway, hip-hop, country, whatever.
