+Since Mup requires its input in a fairly strict format, when a song is put
+in, it may contain "typos." Generally, the error messages that Mup prints
+will give you an idea of what is wrong. However, sometimes Mup is not able
+to recognize that something is wrong until some distance beyond the actual
+error. If you can't find anything wrong with the line that Mup lists as
+being in error, try looking at the end of the previous line, or even earlier
+lines. Some of the most common problems are missing semicolons and missing
+quotes. Missing quote marks tend to be especially confusing to Mup, and may
+cause many error messages, even though there is only one problem.
+Another common problem that may cause a very large number of error messages is
+forgetting to state "music" to enter music context.

+Often listening to

+is much more effective at spotting things like wrong notes and missing
+accidentals than trying to find them by eye.
