In Tune thy musicke to thy hart: The art of eloquent singing in England, 1597–1622 (Buffalo: University of Toronto Press, 1993; RILM Abstracts of Music Literature, 1993-4111) Robert Toft cites John Bulwer’s Chirologia, or, The naturall language of the hand (above, 1644) as a source for rhetorical gesturing that may apply to the performance of English art songs from this period.
“Gesture in the English lute-song” by Rosemary Carlton-Willis (Lute news 94 [August 2010] pp. 8–12; RILM Abstracts of Music Literature, 2010-17302) gives concrete examples of the use of gestures in performing this repertory, and includes a comparison with South Asian ghazal singing, which also has a gestural tradition.
Below, Nusrat Fateh Ali Khan demonstrates South Asian chironomia.
