This rule corresponds to the common practice in the 20th century. This rule
prints the same accidentals as @code{default}, but temporary
accidentals also are canceled in other octaves. Furthermore,

-@findex modern-cautionary
+@funindex modern-cautionary
This rule is similar to @code{modern}, but the ``extra'' accidentals

accidentals. They are printed in reduced size or with parentheses

+@funindex modern-voice
@item modern-voice
This rule is used for multivoice accidentals to be read both by musicians
playing one voice and musicians playing all voices. Accidentals are
typeset for each voice, but they @emph{are} canceled across voices in
the same @internalsref{Staff}.
-@findex modern-voice-cautionary

This rule is the same as @code{modern-voice}, but with the extra

some of them are typeset as cautionaries.
@item piano
-@findex piano accidentals
+@funindex piano accidentals
This rule reflects 20th century practice for piano notation. Very similar to
@code{modern} but accidentals also get canceled
across the staves in the same @internalsref{GrandStaff} or
@internalsref{PianoStaff}.
@item piano-cautionary
-@findex #(set-accidental-style 'piano-cautionary)

Each context can have different @emph{properties}, variables contained

Contexts form hierarchies. We want to hang the @context{ImproVoice}
