This chapter deals with pen interaction and its use for musical notation composition and editing. The authors
first present existing pen-based musical notation editors and argue that they are dedicated to classical
musical notations and are often constraining for the user. They then focus on their generic method that
is in particular based on a formalism that models how to interpret the strokes drawn in online structured
documents. To analyze an element, it models a coupling of a global vision (its position relatively to the
other elements of the document) with a local vision (its shape and that of its components). The authors
also present the hand-drawn stroke analyzer associated to this formalism. Finally, they demonstrate
how the presented method can be used to design pen-based systems not only for classical musical score
notations, but also for plainchant scores, drum tablatures and stringed-instrument tablatures.

computer systems the same way as a sheet of paper.
Figure 1 presents a tablet PC, which is a computer
system with such an interaction: the user writes
musical scores in a traditional way by drawing the
symbols on the screen. This system is an example
of system developed thanks to the methodology

This chapter deals with a new computer system
approach, based on pen interaction, for music
composition and editing: thanks to a pen, the user
creates and modifies digital documents by drawing
on a touch screen. The use of a pen is very intuitive,
because it reproduces the “paper-pen” metaphor,
