I have been using the song «Humano» by Lido Pimienta for years after seeing it on Zachary Jones´ fabulous website. (Click here for a link to Zachary Jones´ post about this song.) I made this video of the song to visually reinforce geography by showing country names and images as she sings each nationality, as well as conjugations of SER and adjective agreement (humano vs. humana). I have also found that projecting a visual aid helps keeps students focused during such a soothing song. Enjoy the video!
