“Is goyishe music really ok”
We’ve had a lot of discussion regarding this issue in other chat forums.
First, one has to define “Jewish” and “goyish” music. Much music of non-Jewish origin has been appropriated by Jews even for liturgical use; for example, the most common tune for “Maoz Tzur” is a German tune that Martin Luther harasha used for a Christian hymn.
And it is difficult to find ANY Jewish music that is not influenced by non-Jewish styles. I’ve mentioned the atonal music of Arnold Schoenberg; it is truly like no music every previously composed. Yet even Schoenberg himself insisted that he was following in the tradition of Johannes Brahms. (And you will never hear Schoenberg played at a simchah.)
