Changes in how you hold your lips (embouchure) can really affect how your brass instrument sounds. Here’s how:

1. Pitch Changes:

   • If you tighten your lips, the sound can get higher. This can help you reach those tricky high notes, but the sound might feel weak.
   • If you relax your lips, the sound usually goes lower, but it might be harder to play the right notes.

2. Tone Quality:

   • If your embouchure is steady, you’ll get a fuller and richer sound. But if your lips are too loose, the music might sound airy and unclear.
   • On the other hand, if you tighten your lips too much, it could make a strained and sharp sound.

3. Consistency:

   • Finding the right balance with your lip position makes a big difference. If you keep adjusting how you breathe and how your lips sit, you’ll get better sound and a warmer tone.

In short, trying out small changes with your embouchure can help fix pitch and tone problems. This can make playing your instrument a lot more fun!
