Charlie,
One of the plus points out here is weather, as you know. It's wonderful to be able to play outside in January.
I'm concentrating on articulation with my current crop of students. As you know, we have a pretty vibrant trumpet culture at CalArts and there are more than a few around here that have worked flexibility studies past double C (Wayne Bergeron is subbing for John Fumo, our regular jazz guy, this term and is amazed

). The next step is to apply the same principle while articulating -- hard for some.
Onward,
EC
