Kazoo That Tune

In Kazoo That Tune players try to hum tunes with their kazoos for they teammates to guess.
One player each round is the "kazoo artist" and gets two minutes to hum their way through as many tune cards as possible.
Each card features two different pieces of music; an easier piece and a harder piece. The easiest one grants 1 point and the other 2 points.
After a certain numbers of round (determined from the start) the team with most points is the winner!
