In 6/8 time, each measure contains six eighth notes. We are often told that therefore there are six beats in 6/8 time.
But when my band plays a piece in 6/8, the conductor counts in two. Also, the tempo is often denoted with a dotted quarter note next to it; and I once read an SE post (I don't remember where) claiming that 6/8 time does not mean six eighth notes, but rather two dotted quarters.
So are there really only two beats, or are there six?
