Make sure that if its the barre version (which is probably is) that your left hand is straight up and down. Try not to have your wrist crooked in any way as this is really hard on the meta-carpals I think they're called?

Anyways, put a lot of focus into the index finger for the barre, and less focus on the other fingers for now. This will help you develop strength and good form, because chances are that if you are getting any buzz its going to be coming from that index finger, which will require the most strength. Again, make sure that your wrist and the index finger are straight up in down in a line from top to bottom. Hope this helps
