Certain bird species are known for their ability to mimic sounds, including musical tunes. The lyrebird, for example, is known for its impressive ability to mimic natural and artificial sounds, including chainsaws and camera shutters.
Elephants are capable of producing low-frequency sounds that can be described as musical. These infrasound vocalizations are often too low for the human ear to detect but are used by elephants for communication over long distances.
Whales and dolphins are known for their complex vocalizations that can be considered musical. Humpback whales, in particular, are known for their intricate and repetitive songs.
Cows have been observed producing vocalizations that can have a somewhat melodic quality. The sounds vary and can include low moos and bellows.
Gibbons are primates known for their vocalizations, which can include melodic and rhythmic elements. Their calls are important for communication and mate attraction.
In scientific studies, mice have been trained to produce sounds that, when manipulated, resemble musical notes. While this is more of a controlled experiment, it highlights the vocal abilities of certain animals.
Bottlenose dolphins in captivity have been trained to interact with musical instruments, such as keyboards. They can be observed creating sounds by pressing keys with their noses or flippers.
Some parrot species, such as the African Grey Parrot, are known for their ability to mimic human speech and various sounds, including musical tunes.
