+          with four quarter notes, two with filled heads, two with unfilled 
+          heads, where first the stem is up and then the stem is down. After 
+          that, each note head style is printed with a half note (should have 
+          an unfilled head by default). Finally, the Aiken note head styles are 
+          tested, once with stem up and once with stem down.</miscellaneous-field>
