+FIXME: Move the following words and example into Tweaks or
+somewhere more suitable, leaving just a ref here. -td
+
+Ways of correcting horizontal placings are described fully 
+in the Notation Reference.  
+We introduce just one here, the @code{force-hshift} property of 
+@code{NoteColumn}.  The lower two notes of the first chord (i.e,
+those in the third voice) should not be shifted away from the
+note column of the higher two notes.  To correct this we set
+@code{force-hshift} of these notes to zero.  
+The lower note of the second chord is best placed just to the 
+right of the higher notes.  We achieve this by setting
+@code{force-hshift} of this note to 0.5, ie half a notehead's 
+width to the right of the note column of the higher notes.
+
+Here's the final result:
