Hello fellow trumpet players! I'm struggling quite a while now with my trumpet playing. I've sought help with my teacher, but it's hard to get answers from someone who never experienced any problems of this kind. I think I'm doing (I'm pretty sure) the valsava maneuver, when playing the trumpet. I have big problems starting a phrase, I just can't bring myself to start with a sure tone and sound, I'm always hesitating and missing the first couple of notes. I've been avoiding tonguing also, because it became such a big issue. I can play quite well legato, but when the tongue comes into play it all becomes so hard. And it just became a problem that isn't acceptable any more. I read many posts about this, but haven't found any good suggestions or exercises to get rid of this. I'm also very interested what you guys think about concentration and calmness.. any suggestions how to work on that too (yoga, meditation, autogenic training)? Thank you for your help.
