Changing context definitions
The most common way to define a context is by extending an existing
context. You can change an existing context from the paper block, by
first initializing a translator with an existing context identifier:
\paper {
\translator {
context-identifier
} }
Then you can add and remove engravers using the following syntax:
\remove engravername \consists engravername
Here engravername is a string, the name of an engraver in the
system.
\score { \notes {
c'4 c'4 }
\paper {
\translator { \StaffContext
\remove Clef_engraver
} } }

You can also set properties in a translator definition. The syntax is as
follows:
propname = value propname \set grob-propname = pvalue propname \override grob-propname = pvalue propname \revert grob-propnamepropname is a string, grob-propname a symbol, value and
pvalue are Scheme expressions. These type of property
assignments happen before interpretation starts, so a \property
command will override any predefined settings.
To simplify editing translators, all standard contexts have standard
identifiers called nameContext, e.g. StaffContext,
VoiceContext, see ly/engraver.ly.
