What are the universal features of music? We collect ethnographic text and audio recordings from all over the world. We use them to determine the behavioral, social, acoustical, and musical features that characterize the world's songs. This provides a public resource to advance the scientific and humanistic study of music.
Music is a signature of the human experience. A ubiquitous, ancient, and uniquely human activity, music, and especially song, appears in most human cultures with staggering diversity. But two fundamental questions — whether there is underlying structure to the world’s music and how that structure varies across human cultures — have been perennially difficult to address. A key roadblock has been the lack of systematic, cross-cultural information about music. The Natural History of Song addresses this gap.
NHS Ethnography contains nearly 5,000 descriptions of songs and song performances from 60 human societies. It includes some 500,000 words of ethnographic text, including translations of over 2,000 songs' lyrics. A team of researchers obtained texts from the Human Relations Area Files and coded them into more than 60 variables. These include the demographics of singers and audience members; the time of day and duration of singing; the presence of instruments, objects, and special attire; and more. Research assistants also used keywords to describe the events leading up to a song performance, as well as its behavioral context, function, and lyrical content. These data reveal the behavioral and social structure underlying the world's songs.

NHS Discography includes analyses of two Densmore field recordings and several other tracks from the Smithsonian Folkways label.
NHS Discography contains transcriptions and analyses of 118 field recordings from the 30 world regions covered in NHS Ethnography. The songs represent four common social contexts: lullaby, love, dance, and healing. We selected recordings by reviewing published collections of world music, digitizing out-of-print recordings, and contacting anthropologists and ethnomusicologists to obtain unpublished field recordings. Each song was transcribed into music notation. A team of expert musicians then listened to each song while reading the transcriptions and coded the song into 40 variables. For instance, they indicated the song's tempo, instrumentation, melodic contour, and whether the song has a clear tonal center. These data reveal the underlying acoustical and musical structure of the world's songs.
What will we learn from the Natural History of Song? For now, we have a couple of big questions:
What sorts of songs appear regularly across human cultures? Anthropologists have observed lullabies, dances, and religious music in many societies, but we don’t yet know what other core domains of human song exist — or whether a set of core domains exists at all. NHS Ethnography will help to answer these questions.
Within a domain, what do songs sound like? Psychologists have observed that songs for babies tend to share some features, like the slow tempi and falling melodic contours of lullabies, but we don’t yet know whether those features turn up reliably worldwide — or what sounds define other song domains. NHS Discography will help to answer these questions.
Eventually we aim to create a modular, open-access platform where scholars can collaboratively annotate and expand the Natural History of Song, and where anyone can rigorously test many other ideas about music.
