I think it would hurt if you had a $2-3,000 Bach, Schilke....... too. The point is, I got the job done and even although it was sub-optimal, the musical message remained intact. I wish many of the young posters here would get the idea out of their head that the horn determines anything. The audience could care less about dark, light, high, low, loud, soft. They are there for the show and OUR PLAYING STYLE makes that work or not. If we do not have heavy duty high chops, we simply play an octave lower and nobody notices. Immaturity would make us want to "prove something" and crack a note rather than keep the musical big picture intact. Build solid habits on whatever horn you have. If your sense of intonation, dynamics, rhythm and musical line are in order, YOU will have made somebodies day.
