Ambitus after key signature
By default, ambitus are positioned at the left of the clef. The \ambitusAfter function allows for changing this placement. Syntax is \ambitusAfter grob-interface; see Graphical Object Interfaces for a list of possible values for grob-interface.
A common use case is printing the ambitus between key signature and time signature.
