What do you think is necessary to play the piano in a coffee shop?

At least 8 to 10. Music depends on the style of each coffee shop. Master at least 10 songs. You prepare a song 1 2, and the guests are not bored. The manager has a headache as soon as he sees you. Play some popular songs that many people have heard, such as fairy tales. It's difficult and romantic to love someone. The Maiden's Prayer by Ba Darce Fusca, a famous foreign track. I searched clayderman's Dream Wedding online. More work, more gain. It depends on the grade of the coffee shop.
