Could be, but for an example, Hamburg is 25% more expensive then berlin when it comes to living (Apartment) and up too 10 % more expensive for food. You would barely be able to survive on 1800 a month (if that's the brutto).
1100 is the take home pay per week. A friend of mine is already over there on a job and that's his salary. This is quite normal for civil construction and actually a lot less than in Australia, for example. Sorry, a bit off-topic as you're talking about artist salary, but I just thought it no harm to throw in a comparison…
