Las cabezas de nota de notación fácil utilizan la propiedad
@code{note-names} del objeto @code{NoteHead} para determinar lo que
aparece dentro de la cabeza.  Mediante la sobreescritura de esta
propiedad, es posible imprimir números que representen el grado de la
escala.

Se puede crear un grabador simple que haga esto para la cabeza de cada
nota que ve.
