“A Song of Our Warming Planet,” came about following a conversation Crawford had with geography professor Scott St. George during an internship. St. George asked Crawford about the possibility of turning a set of data into music. Crawford used an approach called data sonification to convert global temperature records into a series of musical notes. The result is a haunting sequence that traces the warming of our planet year by year since the late 19th century. During a run of cold years between the late 1800s and early 20th century, the cello is pushed towards the lower limit of its range. The piece moves into the mid-register to track the modest warming that occurred during the 1940s. As the sequence approaches the present, the cello reaches higher and higher notes, reflecting the string of warm years in the 1990s and 2000s. (source).
