Hi Manny, I have not write for quite a long time due to my work. I have a problem when playing with the Bb. I started when I was a child with an old small bore C rotary trumpet and played that trumpet for many years until Dad could buy my first Bb. Based on that the Bb wasn't my best choice never. I had never problem with register, but in the middle range E and F in the staff the notes are strangled, thin and the throat ( or the back of the tongue you may say ) is tight and I miss a lot of first attacks in this register due to tension. The curious thing is when I use the mute or the C or the Eb or the Picc those problems do not happen. Do you think that a more tight equipment to emulate high trumpets will help or do you have any other suggestion. Thanks for your help, and sorry if it is a topic covered somewhere else. Saludos.
