I want to do piano accompaniment in hotels or restaurants, but I don't know how to work hard.

Being a piano player in a hotel is not as demanding as being in an entertainment place. You don't need to be too harsh, musical theory and improvisational accompaniment ability, as long as you pass the sight-reading test. . . It is probably enough for the piano to reach level 6 or so. . . Because the piano is played in the hotel, there will be no guests to order songs, so you can play it as you like, as long as there is music, just play it according to the music. . . If you are a pianist who accompanies live in an entertainment venue, you will need a lot of songs and improvisational accompaniment skills. . . That is to have the ability to "play with points, play with singing". . .

You don't need to play the piano well in a hotel. The main thing is that sight-reading should reach a certain level. . .
