I watched this video from K.O. and it really struck a chord. So many young players are ‘trained’ to accept that certain models of instrument or mouthpiece will be the correct ones for them to achieve their goal. Ignoring key factors such as sound quality, intonation and comfort in order to arbitrarily prescribe equipment seems so backwards. Your trumpet and your mouthpiece should never be something that you are required to battle against, but instead should compliment the hard work that you put in, in the practice room.
Fortunately there are many excellent teachers and makers who are really able to look at the player and equipment as a whole, and help the student to make the best of their talent.
