What counts as treble and what counts as bass?

Treble and bass are musical terms. Treble, alto, and bass are collectively referred to as the sound zone. When speaking or singing in a low voice, if you feel your chest vibrating, this is bass. If you stretch your throat, When you shout loudly or sing in a high-pitched voice, you may experience slight head vibrations and a dizzy feeling. This is high pitch.

Humans control the muscles of the larynx to change the tension and thickness of the vocal cords, causing the airflow to impact the vocal cords to produce changes in vibration frequency, which can produce sounds in three vocal areas: high, medium and low. The high voice area is also called the head voice area, the middle voice area is also called the mixed voice area, and the low voice area is called the chest voice area. In the music industry, there are sopranos, mezzo-sopranos, altos, tenors, baritones and basses, all of which represent different vocal ranges. And women’s voices are naturally one octave higher than men’s voices.

The difference between treble and bass lies in the frequency at which the vocal cords vibrate. The treble has a small amplitude and has a high frequency, and the bass has a large amplitude and has a low frequency. There is an octave difference between the treble and the midrange, and there is also an octave difference between the midrange and the bass. Therefore, the difference between treble and bass is two octaves, and the difference in the sounds produced by treble and bass is relatively large.

Many people are afraid of singing high notes when singing. Indeed, it is difficult to master high notes without professional vocal practice. Some people have the conditions to sing high notes, but some people can only reach the alto range. This is related to each person's voice conditions.
