One of the Mastersingers is the town clerk. His name is Beckmesser. He is a comic figure and Wagner makes him look very silly. Beckmesser is the “marker”. This means something like: an “adjudicator”. When a singer makes a “mistake” (disobeys the rules) the marker puts a chalkmark on the board. When Walther sings his song Beckmesser makes lots of chalkmarks. Hans Sachs is the only person who realizes the beauty of his song. There is a lot of shouting and Walther has to stand on a chair to finish his song.
