It happens to me, often times Ive been referred to as looking like a frog. Its funny, for a long time people told me that i played with a closed sound, and i go off, do everything the same, play my horn in front of a professional trumpet player, and he tells me i have an amazing tone. it blows me away. i think i have trouble blending in with other trumpet players which really sucks, but... ive alway been a fan of solo playing. idk. closed, open? whatevvs, its all about sounding like the people youre playing with id say.
