The Association of Friends of Mozarthaus Vienna provides material and non-material support to the work of the MHV. Its members make it possible to purchase, rent, lend and restore objects exhibited or presented at the MHV on a permanent or temporary basis, and to acquire other items necessary to maintain operation. They support the efforts and concerns of the MHV in general and help to enlarge the membership of the association.

The members take part in exclusive MHV events such as concerts, readings or special guided tours and have the possibility of meeting other members and exchanging opinions with them at special presentations.
