First of all, you actually need to think about what conditions a good song needs. First, you need talent, that's for sure. Some people who are tone-deaf don't mean that they don't want to sing, nor that they don't want to sing good songs, but because they are born with difficulties in grasping the intonation of five tones. Another point is that they have to study the day after tomorrow and get professional training, including how to pronounce, how to pronounce and how to pronounce accurately. Then the last one should be related to the difficulty of the song. If a song is difficult to sing, of course, the probability of singing out of tune will be greater. If a song is easy to sing and requires less skills, of course, the effect is better.
Sean Shaw's song at the Starlight Awards this time is actually more difficult. The name of this song is Yu Nian. An insider once pointed out that he had seen this video sung by Sean. He said that it was really not easy to sing this song in full swing because of the difficulty of tone sandhi, and Sean had nothing to be black about. In other words, the insider admitted in disguise that it was good that Sean could sing to this point.
Besides, Sean didn't study music. Last year, he got angry because he played The Untamed. But he didn't study music systematically and didn't practice it specially. So it is quite normal for him to sing such a difficult song.
About the key of this song, the form, the conversion of high and low voices, if you sing it live, I feel that Sean sings very emotionally, and nothing else is too big. Certainly can't be compared with professional singers, which is a very unrealistic problem.
To sum up, it is not a particularly bad thing for Sean to sing the Star Award out of tune, because he is not a professional singer himself, so it is understandable to sing such a difficult song out of tune.
