The papers of this special issue discuss the question of sketch as a subject matter of aesthetics, in theory and in practice, rather than an art history. The issue of sketch does not necessarily concern with artworks. Thus, in “Sketch as Medium in Collective Musical Creation: The Case of Atlas Lab Taipei 2017”, the authors, Yang Chien-Chang et al., take the schematic musical notations on a sheet of paper as an indispensable practice in order to harmonize all the musicians of an orchestra. In this case, the aesthetic value of sketch is not a step for completing an individual work, but an indispensable element for the construction of a collective artwork. In "Le réseau fluide dans la création en image de Wolfgang Tillmans", Lin Chi-Ming demonstrates the aesthetic function of sketch  in Tilmans’ exhibitions' preparatory maps,  representing a crucial and valuable step of display,  but not being artistic works. In “From sketch to fragment”, Jean-Marie Schaeffer examines the different meanings of sketch in European art to underline the focal points and the divergences between sketch and fragment. Whereas in "Beyond Brush and Ink: Sketch Thought and Practice in Classical Chinese Poetry and Painting”, Johanna Liu argues about the specificities of sketch in Chinese arts, rethinking the tension between making and sketching, as well as the poetic power of incompleteness in Chinese literati's art making. Even though, drawings and sketches are not always artistic, however, as Huang Kuan-Min explains in “Roughness and Sketch: The Barbarian Principle in Arts”, sketches and drawings keep a common rough aspect, related to the birth of an artwork for instance. Far from being a constraint, a preparatory drawing or sketch are therefore an expectation, a promise of something else, though they can be considered as artworks per se. The appreciation of the Taiwanese painter Tsai Shui-lin’s works can be understood in this context, as Tsai Shih-Wei has indicated in "Unfinishedness and sketch consciousness in Tsai Shui-Lin’s Works."
