How much did it cost to hire a drummer in the year 1504?

Answer 1

That's a question that is likely impossible to answer, for several reasons:

1) In 1504, "drummer" wasn't a profession. In Europe and Asia, there were musicians, and those musicians sometimes played percussion instruments. But there were no "drummers."

2) Even if there were drummers, there was no such thing as a prevailing wage anywhere in the world.

3) As the question completely fails to specify a locale, it becomes even more impossible to answer. The cost to hire a musician in France could be completely different than the cost to hire a musician in Japan.

What does this have to do with Christmas, anyway?

Nine (or however many) drummers drumming and a partridge in a pear tree.
