I have attended workshops with university-level teachers.

This is a technique they use. When you're practicing and the music sails to a high note, tell everybody to play to that note and then hold it out.   Listen to it. Does it sound good? If not, use your ears, listen to one another, and make it sound good.

That sounds hard to do, but the musical part of your brain can do it. It cannot explain it to the left temporal lobe, which thinks it has to understand and control everything, but nonetheless the musical part can do it.

Try it.

At the same time, C-flat, I understand your reference to the hospital.
