| I am an opera singer. The house literally shakes when I sing and still no one has the right to tell me to stop. The piano is a much less penetrating
instrument and should pose no trouble for anybody. I recommend contacting the SMPV (Swiss Music Teacher's Association - www.smpv.ch) for details and reading this from Ktipp: | |

You may sing as loudly as you please.
The problem is when you start a commercial activity, students are coming and going, etc. That might not be reconcilable with the residential purpose.
