What level do you need to go to a music roast bar and work as a part-time guitarist in a bar?

If you are a part-time singer, you don't have very high requirements for guitar. You can basically play and sing, as long as you have a good voice. If you are a part-time guitarist, the requirements are higher, at least you should have a good control over basic harmony, improvisation and solo. Because in many cases, it is not what you can perform, but what the customer wants you to perform. At this time, your comprehensive level directly determines whether you can continue to work in this bar. Another guitarist is usually not alone, and other musicians need to cooperate with each other, all of which are related to the quality of guitarists. I hope it helps you.
