1. Alto: its range is e-e2 (or g2).

2. Mezzo-soprano: its range is g-g2 (or b2).

3. Soprano: Its range is c1-c3, b-b2 (or c), c1-e3 (or as high as f3).

Voice area is a part of the sound range, which can be roughly divided into three types: treble area, midrange area and bass area.

In the entire vocal range, the small character group, the small character group 1 and the small character group 2 belong to the middle range. The three groups of small characters, the four groups and the five groups of small characters belong to the high-pitched area, while the large group, group one and two of large characters belong to the low-pitched area.

The divisions of the sound zones of various human voices and various musical instruments are often inconsistent. For example, the high-pitched zone of a bass is the low-pitched zone of an alto.

Expanding the range up and down

Upward expansion refers to practicing one note higher from the note you are most comfortable practicing, that is, roughly starting from the musical notation of 1 to 2. 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.

Downward expansion 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.

Whether it expands 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.
