German is easier to learn than Norwegian or (especially!) Finnish. While there are various bizarre cantonal dialects of German in Switzerland, you can always make High German work -- or French, depending on where you are. In addition, the Swiss learn German, French, and English in school. So mostly you can get along in English as well. Switzerland is also centrally located and so travel (by good trains) to France, Austria, Germany, Italy, etc. is quite straightforward and not expensive.
Just some non-musical and non-academic considerations .
