+attractive.  It includes accidentals, meters, and notes of different rhythmic
+values.  The package builds on the approach used in the @code{harmony}
+package, where the symbols are taken from the MusiXTeX fonts.  But it provides
+a larger range of symbols and a more flexible, user-friendly interface.")
