Hey guys
I've been working for quite some time on my high registers (from G above tuning note to C an octave above tuning note), but the tone quality and accuracy hitting the right note is still poor.
Which kind of exercise do you think if good for consolidation of high registers? I have tried chromatic,full tone scales and intervals for high registers, but they do not seem to be showing results. I acknowledge that consolidating any notes is hard in the begining, however which exercises will be more efficient? Any idea?

long tones and lip slurs.
make sure that you breathe nice deep and easily. when playing up high remember not to use pressure and always remember to have a nice Core to the sound. I try and imagine the core of a sound like a tennis ball. it is round solid with a small glow around it. Remember that focusing the air is a major point of playing up high well. an excersise I use is to hold up my index finger level with my mouth and focus on blowing just on the top join of my finger keeping the air free and consistent. zthis creates that core and stops the not from goin splat out of the end of the bell. also remember to think of the notes as tho they are on a line not thinking that they are high just play it and dont worry about it
remember the key to playing well is to play easy. and fell easy.
