Are nuns allowed to dance

Answer 1

There are two different kind of religious sisters in the Catholic church. The first, which most people are familiar are sisters, not nuns. They are under simple promises which are renewed each year. These are the sisters one commonly finds working in a parish, teaching school, etc., they mostly live in convents or on their own depending on how their Order is set up. The other kind of religious sister is a nun, they live in monasteries and usually have pontifical enclosure (there are bars on the windows, and people are normally not allowed in). Nuns are under solemn vows which bind their whole lives long.

Both kinds of sisters would be allowed to do whatever their order allows, and their Mother Superior, or Abbess allows. St. Teresa of Avila, the superior who reformed the Carmelite Order in the 16th century and started the Discalced Carmelites used to promote dancing with tamporines when the sisters where "caught up in the spirit".
