\accidentalStyle dodecaphonic

[Freeman Gilmore]

Would someone please explain  \accidentalStyle dodecaphonic in the following:

\score {
   \new Staff { \treble }
    \layout {
     \context {
      \Score
       \accidentalStyle dodecaphonic
     }
   }
 }

This is what found in the manuals, "A predefined command such as
\dynamicUp or a music expression like \accidentalStyle dodecaphonic"

Thank you,  ƒg
