Embochure/Apeture

Hi Allen, a few questions.

1. Do you keep the your embochure/upper planted on the mouthpiece as you go to a higher register or as your lips tighten does the top of your mouth pivot? I'm struggling with this.

2. I know that you hold your right thumb between the first and second valve casing. Is your thumb straight or is it bent?

3. Are you applying pressure on the right thumb as you play for your fingers to move faster / quicker or is it just for stability?

Thanks
John

!) My upper lip is basically in the same place for all ranges. I don't tighten my lips. I actually relax them in the middle. I don't know what you mean by "top of the mouth pivot" - sorry.
2) My thumb is placed comfortably. WIth my hands that means bent.
3) My entire right hand is relaxed when I play very quickly. I do use aggressive down stroke on the valves.
Hope this helps.

Thanks Allen. Your answers bring some clarity.

Hi Allen, btw the comment I made about tightening of the lips comes from H.L. Clark "Technical Studies for the Cornet" on pg.5 under first study. It says "Tighten the lips slightly in ascending lines, loosen them in the descending lines" Maybe I misunderstood this. The word pivot I've heard from my trumpet instructor as well as others is when you move the horn/bell up when playing high and lower when playing lower notes. I guess this was also wrong. The primary problem I'm having which I discovered from my teacher is I have 2 embochure's. I am now correcting this knowing your embochure should stay the same and not be reset when changing registers. Thanks again.

Sorry, I meant the horn moves down when playing high and high when playing low. In any case it's wrong
