I noticed myself doing something funny recently. It turns out that without even thinking about it my subconscious demands that after I conduct a Gregorian Chant, ie. for Offertory or Communion, using chironomy that the polyphony piece immediately following be conducted using the same type of gestures rather than the patterned 4-4 or 3-4 (or whatever) time signature it may be in. I suppose it works due to the nature of sacred renaissance polyphony... I usually find an appropriate part in the piece to switch, if I even think about it.

Anyone else? :-)
