The aim of this paper is first to present the results of how first year students of architecture are exposed through an introductory course, (2nd semester, University of Cyprus), to ways of visualizing relations in time rather than objects in space. Further on, the paper will link such pedagogical approach to a broader thinking of making explicit relations, therefore performances in architecture and especially in "architecture as practice". Usually students, through architectural education, become acquainted with means of representation of objects in space. This approach quite often, leads to "architecture as building" approach (object-based design) rather than "architecture as practice" one, (process-based design). The difference between the two is that the latter takes into account not only the object to design but also the systems of actors who are involved in the design process and their priorities. In order that architects find a decisive role within "architecture as practice" approach, they need to be able to visualize relations between project actors, their complex environments, their priorities and the design outcome. Such approach gives to the notion of performance a prominent role and of that of diagram an important tool in communicating such information, especially on how performative are relations between project actors in a process based design approach. To accomplish such objective the workshop uses the 'cosmos' of musical instruments. Every year the workshop focuses on different types of musical instruments in different kinds of context: wind instruments during the rehearsal of Cyprus State Orchestra, chord instruments in "Buena Vista Social Club" movie of Wim Wenders, percussions in "You Tube' video music clips.
