Umm...I'm not sure, but this is what I was told.
Some of the basic things that go into being able to hit the high notes are
1. Embouchure
*2. Mouthpiece
*3. Reed Strength and Placement on the mouthpiece
4. Air flow
*Assuming you play a woodwind other than flute or double-reed
1. Your embouchure gradually gets tighter as you go up the scale for pretty much any woodwind instrument. I'm assuming you play woodwind since you ARE posting this question in the woodwind subforum. If not, move this topic ><
2. Mouthpieces are all different. They range from size and brand. Each brand fashions their mouthpieces differently and also make different grades. My sax mouthpiece is a Yamaha and is (as told by my band director) a professional grade mouthpiece. And it took quite a while to get used to. Point is, all mouthpieces have minute differences that can alter tone and airflow.
3. As we all know (at least I'm assuming we all do) reeds also, like mouthpieces, come in different brands and strengths. Find one that works for you at a strength you can play easily at without trying too hard.
The placement of the reed also makes a different. Put it too far up on the mouthpiece or too low can make playing hell. Trust me. I wondered why my jaws died on me after only a few minutes of playing when I found out that if I placed my reed just a fraction lower my jaws could last for almost an hour of playing.
4. Exactly what it sounds like. Control your airflow. Your playing position also contributes to your airflow as well as how you position your tongue inside your mouth while you play.
Also, just practice. ^^v
