1. Alto range: small character group, one small character group, two small character groups (c-b?); bass area: large character group, one large character group, two large character group (A?-B).

2. Sound range refers to the total range of sounds that an instrument or human voice can produce. For example: the piano's range is A?-c5; the soprano's range is generally c?-c?; the bass's range is generally E-e?. The narrow range usually refers to the total range of part of the sound sequence, or the total range of sounds used in a certain musical work. For example, the range of the national anthem is d?-e?.

3. Each sound zone has its own unique characteristics. The sound zone plays an important role in musical performance. To a certain extent, it can fully express the musical emotions that the composer wants to express. The treble area is crisp, loud, and sharp with emotional color. The characteristics of the midrange are not very obvious, and it generally serves as a melody. The bass area has a heavy, thick and solid feeling.

Extended information

1. Upward expansion refers to practicing from the most comfortable note to one note higher, that is, from about 1 to 2 of the musical notation. You should start with the weaker sounds. Carefully maintain the correct breathing state, pay attention to waist control, Dantian control, and mouth control, and then gradually increase the volume to normal. Once you have a certain experience, expand up a note.

2. Expanding downward also means practicing from the sound you are most comfortable with to the next sound, starting from the weaker sound. When extending downward, be particularly careful not to strain your neck, hold your throat, or press the base of your tongue. Try to maintain the correct state of control.

3. No matter whether you extend it upward or downward, do not pronounce it in a singing manner, but pronounce it with a speaking mentality. The key is to maintain the "bead" and "ball" feeling in the front of the hard palate.
