= "Controlling the appearance of tremolo slashes. Property
@code{slope} is self-explanatory. Property @code{shape} determines
whether slashes look like rectangles or like very small beams. Setting
these properties directly cause all slashes behave in the specified way.
However, one usually wants the slashes to behave differently depending on
whether the note has flags, beams or only a plain stem. That's what the
@code{style} property is used for: it sets shape and slope depending on
the situation. There are two styles defined: @code{default} and
@code{constant}."
