Hello, teacher! My guitar, a mushroom, how to sing the soundtrack of the first section #fa, fa, is it do bdou?

This is a gtp problem. When I play music, I use the original #F key, but whether I write key signature or not, he always shows it this way. I clicked the guitar fingerboard and clicked the keys, which may not be the case (I don't know, I haven't tried it).

However, the fingerboard of the guitar is more important. After all, it is played with a guitar. If the correct symbol is used, he should write it in the fourth room. He must sing si instead of bdo. It seems that you will ask this question. Good idea! Hmm. How interesting
