Newswise — Musicians akin to Jimi Hendrix and Eric Clapton are thought-about virtuosos, guitarists who might make their devices sing. Drummers in west Africa who play hourglass-shaped percussion devices known as dùndúns could make their instrument not solely sing, however discuss. New analysis printed within the journal Frontiers in Communication is among the first to indicate the excessive diploma of acoustic correlation between these speaking drums and the spoken Yorùbá language.
Dùndún drumming is a musical-oral custom the place expert drummers, manipulating the depth and pitch of the instrument, can mimic Yorùbá, a tonal language primarily spoken in southwest Nigeria. Dubbed ‘speaking drums’, dùndúns can be utilized as purely musical devices or what scientists discuss with as speech surrogates, imitating the three tones of the language.
The authors of the brand new paper describe how they analyzed and in contrast 30 spoken and sung verbal snippets with corresponding drum and tune excerpts. They discovered that the dùndún very precisely mimics the microstructural traits of Yorùbá vocalization straight, whereas the constancy decreases when the drums are used purely for music or much less direct communication akin to tune. The scientists additionally distinguish 4 modes via which the speaking drum connects music and language – rhythm, singing, drum talking-performative and drum talking-direct.
New understandings between music and speech
Equally essential, the acoustical evaluation demonstrates how finding out non-western cultures can enrich the best way scientists extra typically perceive the connection between music and speech, in addition to how people course of them, in response to lead creator Dr Cecilia Durojaye, a researcher and musicologist affiliated with the Division of Psychology at Arizona State College.
“These sorts of multicultural findings are helpful for contemplating deeper relationships and understanding of varieties of auditory communication and the evolution of language and music,” she stated. “The speaking drum is exclusive in that it has a foot in each language and music camps, and since its existence reminds us of the skinny boundary between speech and music.”
Whereas the speaking drum is particular to the Yorùbá language, speech surrogacy in music happens throughout cultures, so the analysis can contribute to how scientists perceive the phenomenon typically and within the Yorùbá tradition particularly, Durojaye defined.
The examine concerned evaluating the timing patterns between recorded drum excerpts and clips of speech and tune from Yorùbá vocal performers {and professional} drummers. The researchers additionally extracted particulars on frequency and depth of the recordings to grasp the structural commonalities in these totally different types of communication.
Functions of speech surrogacy
“Our discovering that verifies distinct drumming modes various between musical capabilities and speech surrogacy helps make clear how the speaking drum is utilized in particular useful methods regarding several types of communication,” Durojaye stated.
Speech surrogacy serves quite a lot of capabilities, from disseminating oral historical past to reciting poetry and proverbs. “By means of musical devices like these drums, one can know the historical past of a specific tradition or a type of data dissemination, in addition to features of how the folks assume, their perception programs and values, and what’s probably essential to them,” she famous.
There may be nonetheless a lot that scientists don’t perceive about how these speech surrogate programs function by way of the formal linguistic properties they include, Durojaye stated. For example, how does every mode seize and encode tone and syllables? Or how is the knowledge transmitted on a syntactic or semantic degree? And what’s the extent of their overlap with musical properties?
“Our examine, which focuses on the acoustic properties of spoken, sung and drummed varieties, represents one of many first steps in the direction of understanding these varied constructions,” Durojaye stated. “We proceed to discover this distinctive instrument, which has the potential for enhancing our understanding of music and language processing, particularly from a non-western perspective.”
