As a general rule I conduct with one hand, that way I can be a semiconductor. I also do it while snorkeling, that way I can be a coral conductor.

Seriously, Prêtre conducted with a light touch in an era when conductors tended to try to control orchestras with an iron fist. His love of Debussy, and the way he would evoke the music's emotion out of the performers, can be seen here. RIP, maestro.

Many did so out of anger: they were thermal conductors.
