Conducting is
very interesting indeed! I have actually taken about two or so years worth of conducting (maybe more?) including some performance experience outside of the classes.
Anyway, I am by far no pro, but the things that have really stuck with me are very similar actually to how I would think on piano playing.
One of the things I remember most and believe strongly in, is in the motives behind the gestures. Through experiences as an observer, choir member, and conducting student, with some truly great conductors, this point is one of the most important things I have found in it all. The more movement the conductor gives, the heavier the sound tends to be, so it seems one should decide for certain as to why exactly the gesture is needed. In conducting, I stongly believe in the
less is
more scenario.
Of course thorough study of the score is valuable. Learning
all of the voice parts/instrumental parts thoroughly and knowing how they should fit together in order to really be of help when it is needed once the ensemble gets together. Knowing what exactly is the sound you are wanting to hear. How can you indicate this in gesture? What do you need to do?
Observe a lot! Mimic good examples just to get the feel. Practice in front of the mirror. Don't forget that your facial expressions have a HUGE impact on the ensemble, especially if they are well trained. I also think that friendliness can go a REALLY long way in conducting. People are generally very willing to respond to a conductor who treats them like intelligent and feeling people.
If I remember correctly, you are in choir yes? Observe closely your director and ask questions after class. You are in Uni, yes? Observe the other conductors in school as well.
Of course, the best way to be considered a good conductor is to use only the best musicians who already know exactly what to do and do it

.
Anyway, just some thoughts.
