Zoomusicology (/ˌzoʊəmjuːzɪˈkɒlədʒi/) is the study of the musical aspects of sound and communication as produced and perceived by animals. It is a field of musicology and zoology, and is a type of zoosemiotics. Zoomusicology as a field dates to François-Bernard Mâche's 1983 book Music, Myth, and Nature, or the Dolphins of Arion (published in English in 1992), and has been developed more recently by scholars such as Dario Martinelli, David Rothenberg, Hollis Taylor, David Teie, and Emily Doolittle.

Zoomusicology is a separate field from ethnomusicology, the study of human music.

Zoomusicologists in a wide range of fields including music, semiotics, philosophy and biology conduct zoomusicology research. This is because the field of zoomusicology is so broad and reaches many disciplines. Musician and zoomusicologist Hollis Taylor has conducted an extensive study of the Pied Butcherbird (Cracticus nigrogularis) over the past 15 years, including interdisciplinary research with philosophers and scientists. Clarinetist, and philosopher David Rothenberg plays music with animals, and has written books on the relationship between bird, insect, and whale song and human music. Composer Emily Doolittle has written numerous pieces based on animal songs, and has published interdisciplinary music-science research on the hermit thrush and the musician wren. Heavy metal bands such as Hatebeak, Caninus, Naegleria Fowleri, and Boar Glue have released music fronted by a grey parrot, a pit bull, an Amazon parrot, and a guinea pig, respectively. Susan Belanger has also contributed to the field of zoomusicology, with her work on soft song in the Asian corn borer moth (Ostrinia furnacalis) and its relationship to the initiation of mating behaviour. Researcher Patricia Gray has examined the music that can be seen in whales and songbirds. This list is by no means all encompassing, but simply lists some notable members of the zoomusicology research community.

There have been several musicians over the years who have performed with or for animals, hoping to elicit responses. Examples include: the song "Seamus" from Pink Floyd's 1971 album Meddle featuring Steve Marriott's Border Collie Seamus howling along to an acoustic blues song. The performance was repeated in "Mademoiselle Nobs" for the film Pink Floyd: Live at Pompeii (1972) with a different dog, Nobs. Paul Horn played flute to Haida, an orca living at Sealand of the Pacific in Victoria, British Columbia on his album Inside II (1972), though the response was merely spyhopping. Paul Winter played his saxophone for both wolves (who howled) and gray whales (who did not) on his album Common Ground (1978). Composer Jim Nollman plays guitar and wooden flute to such species as whales, wolves and turkeys. David Rothenberg, a clarinetist, has played to humpback whales, cicadas and birds (2005-2013) with no apparent response.

Composer David Sulzer, under the name David Soldier and the Thai Elephant Orchestra, built giant percussion instruments for the elephants at the National Elephant Institute at Lampang to play, with minimal human direction.

Composers have long evoked or imitated animal sounds in compositions, including Antonio Vivaldi's The Four Seasons (Vivaldi) (1720), Jean-Philippe Rameau's The Hen (1728), Camille Saint-Saëns's The Carnival of the Animals (1886), Jean Sibelius's The Swan of Tuonela (1895), Frederick Delius's On Hearing the First Cuckoo in Spring (1912), Ralph Vaughan Williams's The Lark Ascending (Vaughan Williams) (1914), Ottorino Respighi's Pines of Rome (1924) and The Birds (1928), Ferde Grofé's Grand Canyon Suite (1931), Olivier Messiaen's Catalogue of the Birds (1956–58), George Crumb's Vox Balaenae (Voice of the Whale) (1971), and Pauline Oliveros's El Relicario de los Animales (1977).

Some modern composers have included recordings of animals in their scores, including Alan Hovhaness's And God Created Great Whales (1970), Einojuhani Rautavaara's Cantus Arcticus (1972), Gabriel Pareyon's Invention over the song of the Vireo atriccapillus (1999) and Kha Pijpichtli Kuikatl (2003).

In 1960 American engineer Jim Fassett put together an album of slowed-down and re-arranged bird songs called Symphony of the Birds. Novelty songs pieced together from the sounds of dogs (The Singing Dogs) or cats (Jingle Cats) enjoyed brief popularity in the 1950s and 1960s. Field recording expert Bernie Krause in 1988 released a single ("Jungle Shoes"/"Fish Wrap") and an album (Gorillas in the Mix) of songs composed of animal and nature sounds. The Indian zoomusicologist, A. J. Mithra composed music using bird, animal and frog sounds from 2008 until his death in 2014. In that same year, New York beatboxing artist Ben Mirin began incorporating animal sounds into his beats.
