1, girls' voices should be refined into boys' voices, and pay attention to the voice of * * *. You will feel the leading role of the oral cavity and pharyngeal cavity.

2, the sound as far back as possible.

3. Improve boys' voices by practicing bubble sounds.

What is the bubble sound:

Bubble sound is a kind of sound produced after the larynx is fully relaxed. Learning it can help you feel the sound hanging on the vocal cords.

In the morning, we lie lazily in bed, yawning, and pronounce this sound from high to low. When we pronounce it to the lowest pitch, we will hear a sound like a series of bubbles. With the adjustment of breath, bubbles can be large or small, thin or dense, a bit like the chirping of frogs and the engine sound of motorcycles.

This is the bubble sound, seemingly simple, but it has a magical effect on the sound. Just practice slowly.

The practice of bubble sound is an important basic training in vocal music learning. Speaking and singing rely on the vibration of vocal cords to produce pitch. Bubble sound is the initial state of vocal cord vibration, and the sound emitted is the lowest sound zone. All sounds come from the sound of bubbles.

It is easy to feel how the sound leans against the vocal cords through the sound of bubbles, and you can also feel the tension of the vocal cords and the resistance to the airflow through the sound of bubbles.
