+There are currently two bugs that are preventing proper horizontal
+spacing when using @code{\magnifyMusic}. There is only one
+available workaround, and it is not guaranteed to work in every
+case. In the example below, replace the @var{mag} variable with
+your own value. You may also try removing one or both of the
+@code{\newSpacingSection} commands, and/or the @code{\override}
+and @code{\revert} commands:
+
+@example
+\magnifyMusic @var{mag} @{
+ \newSpacingSection
+ \override Score.SpacingSpanner.spacing-increment = #(* 1.2 @var{mag})
+ @var{[music]}
+ \newSpacingSection
+ \revert Score.SpacingSpanner.spacing-increment
+@}
+@end example
