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 Voice context. Engravers for key, accidental, bar, etc. form a Staff
context.


You may only see the first example in this document; please download
