In one sentence, describe what the following article is about: They tend to be tensed when hitting high notes.  You might be tempted to raise your chin as if you’re reaching for the note, but this will strain your voice and restrict your vocal cords. Keep your head level. Pull your shoulders back and align your spine in a straight line, extending through the crown of your head. To practice the correct posture, lie flat on your back on the floor or stand against a wall. To sing high notes without putting tension on your vocal cords, aim to use forward placement so that the sound hits the roof of your mouth first. To practice, hum and notice the gentle buzz you feel behind your nose. Press into the buzz to make your sound louder and higher. Open your mouth and imitate a siren, making sure to feel the sound in the same place in your head.As you sing higher notes, the sound will shift toward your soft palate, but try to keep it pointed toward your nose. Begin by singing an “Ahh” sound in your chest voice, and move up the scale. Notice how the pharynx and back of your throat feel when singing in your chest voice.  As you ascend the scale, keep your throat open and try not to let your pharynx move up in your throat. You’re still drawing breath from your diaphragm, but you’re not involving your nasal passages as much as you would when singing in chest voice. Pinch your nose and sing. Though higher notes involve your nasal cavity, you’re not singing out of your nose. Pinch your nose and transition to head voice and falsetto. Work on being able to produce a consistent sound with your nose blocked. The best way to sing in high tenor is to practice repeatedly. By singing songs that force you to consistently hit higher notes you can begin to train your voice and expand your range. Consult a vocal coach to help you as well. Some tenor 1 songs are:  "Alone in The Universe" from Seussical the Musical. "Bring Him Home" from Les Miserables. "The Dentist" from Little Shop of Horrors. "Can’t Take My Eyes Off of You" from Jersey Boys.
Summary: Relax your body, especially your mouth and your shoulder area. Use proper voice placement. Open the back of your throat. Practice songs that have tenor 1 vocals.
