Hey, I thought of a way music can be biology....you know that saying "music is everywhere"????? Well Cicada's (pronounced Sa ka ta's) click their wings to attract females during the summer, and where I live is where the largest Sand Island is in the world, namely Fraser Island. Every summer if you go over there and into the rainforests you can hear one start off and it sounds like a rain stick, so there is music for you in biology.
