If it's two female voices, such as ZLY, it's better. The problem is that they are not even the same sex. How can it be compared? And it is difficult to compare the advantages and disadvantages of two different singing methods. For example, bel canto and modern singing, everyone sings differently. And popularity is not determined by the strength of singing, which is even more difficult to compare.
If you really want to compare, it is recommended to determine the following parameters:
1. range
The more vocal ranges you cross, the stronger your singing skills, and Ayumi Hamasaki is extremely powerful in this respect. _ & lt
2. Accuracy (sex)
Always out of tune is no good ~
3. vital capacity
It can be improved by exercise. Even with the advantage of wide range, it is difficult to play for a long time without the support of vital capacity, which is directly manifested as panting after several songs.
Step 4: Skills
Using certain skills in singing can make up for some shortcomings in voice. It is said that Song Zu Ying couldn't make a sound in the concert in Vienna because she was unaccustomed to the environment, but she completed the performance perfectly with her skills (even cows can sing without their voices = =).
