Given the above summary, write a detailed text in English for it.
You want to do the same thing you did for low notes but for the high end of the scale. Start with a higher note that you have no problem reaching, and ascend the scale key by key, but do not let yourself go into falsetto for this exercise.  If you’re a woman, start by playing a C5 and work your way up from there, key by key. If you’re a man, start by playing and matching a G3. You want to find the highest note you can hit without significantly changing your tone quality or the natural action of your vocal cords. If you hear a break or new breathiness in your voice or feel a difference in how your vocal cords are working to produce a note, then you’ve passed your modal register. Most people can use falsetto, a mode in which your vocal cords remain open and relaxed and vibrate much less, to go lighter and higher than they can in their modal register. Now that you’ve found the highest note you can sing comfortably, relax your vocal cords, and see if you can push yourself a bit higher beyond your normal voice. Use your breathier, flute-like falsetto voice to find the highest notes you can reach without straining or cracking. If you find that you can go further still beyond your falsetto to high notes that sound like whistles or squeals, you may well have a whistle voice, too. Your highest note will fall in that register. Now that you’ve located your highest notes, write them down in scientific pitch notation. Again, you want to track the highest notes you can reach without straining. Some of these notes may not sound wonderful before you’ve given them more practice, but include them as long as you can reach them comfortably. For example, if your highest note in your normal voice is the fourth ascending F on the keyboard, then you would write down F4 and so on.
