First of all, we need to understand the level of people coming to the college entrance banquet. Are they also studying music, or are they just ordinary people?
I thought that since he was a friend of his father’s banquet, he probably wasn’t studying music. Then just choose something that is catchy, melodious, and easy to sing. It’s best if the average person can’t help but sing along after listening to it. "Good Days" mentioned above is good, as are "Hot Girl", "Liuyang River", and "Love in Heaven and Earth". Don’t think that just because you are learning this, you have to sing difficult and impressive songs. In fact, anyone can tell if it’s difficult to sing! Who can appreciate this good thing? I have never heard of it, so people who listen will have a kind of resistance. Just like an opera singer and a pop singer, which one is more popular? I think pop songs would be better. It is necessary to grasp the public appreciation taste.
If the crowd is professional, then choose a song that you are good at and that has some skills in it. But the most important thing is to be good at it! The one who usually sings more and performs the best! Because this will not let others see your shortcomings in singing. Choosing songs poorly is another matter.
Whether it is bel canto or ethnic, the songs are all sung the same way, just in different pronunciation methods. If you sing well, you don't care about these things.
