The very impressive a cappella group Pentatonix offers a free download of one of their pieces at their website. Actual musical notation being offered to the public, I thought - wow, what a concept in the pop realm. Well, I checked it out, and, though the meter signature is six-eight, the first measure is notated with a half note followed by two eighths - in other words, it is written in three-four. Sigh. More questionable command of basic music theory described in the second half of this post.
