I posted this at the site:
Restrictions against music at weddings even existed outside Eretz Yisroel. In the 19th century, the Maharam Shik of Chust in the Ukraine ordered all those who listened to him (which did not include everyone in his community as the Haskalah was on the rise) to not take musicians at weddings. He feared that the levity induced by music might lead to mixed dancing (Likutei Mahari’ch).
