Abstract

Music can affect human health and well-being. This sparked an expanding field of study that focuses on how music might improve animal welfare and facilitate human-animal interaction. A method of producing sound is through music and other animal vocalizations. Birds have a vocal organ called the syrinx in their larynx that holds their vocal cords deeper into their bodies. While humans only have one set of vocal cords, songbirds have two sets, allowing them to generate two distinct sounds simultaneously and in unison. The term "bird song" refers, in non-technical terms, to the musical bird sounds that humans can hear. Loud shouts from world monkeys are the most plausible choice for the model of predecessor for human vocalisation due to structural and behavioural similarities in all non-human primates' vocalisation.
