I had a long conversation with my conductor/director friend at dinner this evening, in which I did not introduce the word chironomy, but did ask if he knew a word that encompassed or described the gestures of choral conducting. He was unaware of any such term. I suspect that its modern use is limited and fairly specific, but that conclusion is based on not much knowledge at all. I have, by email, asked my friend to investigate this term using his insider status in the field, hoping that he will broach the question to colleagues throughout the country. As he is very busy, not much may come of it, but I hope for some response.
