pen-Based sYstems for musIc
composItIon and edItIng WIth
the presented approach

• A pen-based graph editor, that allows to

draw geometrical shapes and to connect
them thanks to arcs; it also enables the user
to write text in the geometrical shapes; the
top of Figure 12 presents two screenshots of
this editing prototype, on the left the user
hand-drawn strokes, and on the right the
corresponding interpreted document.

Thanks to the methodology we present in this
chapter, we have already developed various pen-
based prototypes for the composition and the
editing of structured documents from different
domains:

• A pen-based UML class diagram editor, that

makes it possible to draw classes, represented
as rectangles, and to connect them to model
associations; inheritance and aggregation
are among already available symbols; the
bottom of Figure 12 presents two screenshots
of this editing prototype.

• Pen-based editors adapted to classical musi-

cal score notations, plainchant score nota-
tions, drum tablature notations and finally
stringed-instrument tablature notations. We
are going to present these systems more in
detail in this section.
