Del problema central de la notación, esto es, crear un determinado
símbolo, se encargan los «plugins» o complementos añadidos.  Cada
uno de los complementos se conoce como un grabador. En este
ejemplo, los grabadores se van activando uno por uno, en el orden
siguiente:

- cabeza de las notas,

- el símbolo del pentagrama,

- clave,

- plicas,

- barras, ligaduras de expresión, acentos,

- alteraciones, líneas divisorias, indicación del compás, y armadura.

Los grabadores se encuentran agrupados. Por ejemplo, las cabezas de
nota, ligaduras de expresión, barras de corchea, etc. forman un
contexto de voz, @code{Voice}. Los grabadores de la armadura,
alteraciones, líneas de compás, etc. forman un contexto de pentagrama,
@code{Staff}.

The notation problem, creating a certain symbol, is handled by plugins.
 Each plugin is called an Engraver. In this example, engravers are
switched on one by one, in the following order:

- note heads,


- staff symbol,


- clef,


- stem,


- beams, slurs, accents,


- accidentals, bar lines, time signature and key signature.



Engravers are grouped. For example, note heads, slurs, beams etc. form
a @code{Voice} context. Engravers for key signature, accidentals, bar
line, etc. form a @code{Staff} context.
