1. Correct respiratory support: Correct respiratory support is very important when singing. Learn to take a deep breath, fully inhale the air into the lungs, and then push the air out with your abdominal muscles. This can provide enough support and make your voice more powerful.
2. Practice vocal skills: Practicing vocal skills can help you control your voice better. You can do some basic vocal exercises, such as making a continuous "buzzing" sound, and then gradually increase the volume and tone. You can also try to add some vibrato and pitch changes to the sound to increase the diversity and expressiveness of the sound.
3. Find your own range: Everyone's range is different, find your most comfortable range. After finding your own range, you can practice in a targeted way to avoid excessive use of falsetto to sing high notes.
4. Practice bass: Bass is the basis of singing, so practice bass well. You can try to sing some bass songs, or use some bass practice methods, such as making a low "buzzing" sound, or practicing bass vocalization.
5. Seek professional guidance: If you want to learn singing skills more deeply, you can seek professional guidance. You can find a vocal music teacher or attend some singing training classes to get more advice and guidance from professionals.
In short, changing falsetto to sing high notes requires persistent practice and technical guidance. Through the above suggestions, you can gradually improve your voice and make it more pleasant and explosive.
