The researchers used an underwater microphone, called a hydrophone, and electronic tags on 15 individual whales to record songs from individuals and the whale population as a whole. The whales sang their summertime harmonies mostly at night, getting louder as months passed until reaching a crescendo around October and November. As the whales prepared to head toward warmer water, they began singing during the day.
