Most communs have an annual or bi annual listing of courses to take, that is offered by the commun at reasonable prices. The coursed can range from sport activities (i.e. Tennis), to Bonsai tree care, gardening, Languages, and musical. So visit your local commun website, and you should get some good ideas.

1) Programme des Cours 2017/2018

2) Guide des Loisirs 2017/2018

3) Hiver Automne Programme 2017/2018

4) Sports a Meyrin 'Hiver' 2017/2018

all difference but as examples. Vernier, Carouge, and many communs have the same. 

There was also a program for Cultural and another for the Forum Meyrin, but I was not interested in those programs, but again, the communs have alot of resources.

So just call them for help.

Also for music and culture classes

Dear Dave,

Thank you so much for your advice, but at the moment I am looking for someone who can come to the house.

You can go to the Conservatory (Place de Neuve) and look at the notice board. I think many students teach piano, and probably can come home to you.

I know a very good piano teacher who is English mother tongue but also speaks French and Swiss German. I will PM you her details.

Not sure, but maybe here:musicforkidsgeneva.com
