Most brass players have been told the same thing: “Buzz into the mouthpiece and the instrument amplifies the sound.” But as Los Angeles Philharmonic trombonist Paul Radke explains in this lesson, that’s not quite how it works...

And understanding the real physics behind sound production can completely change the way you play.

Using the trombone as his example, Radke demonstrates how resonance, not pressure, is what truly drives a great tone. The goal isn’t to push air through the horn — it’s to find where your instrument naturally wants to vibrate.

When you do, the sound becomes richer, freer, and more effortless.


Even if you play trumpet, horn, euphonium, or tuba, the same principle applies: every brass instrument has natural standing waves waiting to be unlocked.

By learning to collaborate with your instrument’s resonance instead of fighting it, you’ll gain clarity, endurance, and a sound that feels easy no matter how long you play.
