If you search YouTube humpback whale song (or in English humpback whale song) you will find hundreds if not thousands of results: the singing skills of these cetaceans are known as well as their ability to compose real songs 跨際數位行銷有限公司 with a structure and rhythm . humpback whale songs are therefore highly studied by science but in recent years these studies are slowing down for an unforeseeable reason: there are fewer and fewer males singing.
Interpretation.
