I took up the flugelhorn just over 3 years ago and am struggling to expand my range above the stave. I am told by my fellow band members that it is more difficult with a flugelhorn than a trumpet. Is this true, or, are they just making excuses for me. I have a good instrument and I practice daily. I have tried any number of exercises with little improvement. I am 66 years young, if that has any bearing. I have developed the unfortunate habit of pressing the mouthpiece very firmly into my lips to try and get there and that can't be good.
