Man . What's wrong? Leave Hodor alone, he's my friend.. I would say, you are distorting completely what I said: I said, there is a word in German for making music that does not imply "playing", that's all I said. I did not point to what you answer when being asked which musical instrument you "play". We use "play" in this case only because of the absence of a better word, not because we literally compare the biological behavior "playing" with "using an instrument". And yes, people use "musizieren" in Germany a lot in various cases, for example in school language or when people describe social activities. It is not "stiff" at all by itself, it is how you use apply it. Don't blame me, blame those .... German to the bone Germans.
We have the same in swedish. I guess it comes from the german language. But we say göra musik.
