In the 1960s, Katy Payne became one of the first researchers to discover that whales compose songs. Payne, a graduate of Cornell’s music department, first heard the sounds humpback whales make husband through the work of her then husband. For fifteen years, she recorded and studied the music of two different whale populations, discovering that whales create complex, lengthy sequences of phrases and notes that repeat. At BAM/PFA (2626 Bancroft Way, Berkeley), she’ll deliver a lecture about her work, while Daniela Gesundheit (of the Toronto-based pop duo Snowblink), a choir, and instrumentalists recreate the whalesongs. Payne taught the performers the principles, structures, and techniques of the cetacean-created music using spectrograms and deep listening exercises with audio recordings she took in the field. The performance should be transfixing.
