Music in Disorder is an artistic research project funded by The Swedish Research Council and Stockholm University of the Arts. It is taking place during 2016-2018, is established at The Royal College of Music in Stockholm, and involves a series of concerts, artistic productions, publications, research labs and seminars. The research team is led by pianist/composer Klas Nevrin and includes Anna Lindal (violinist), Katt Hernandez (violinist/composer) and Ricard Österstam (percussionist). We collaborate regularly with guests and other musicians in various ways, especially the octet of improvisers in Revoid Ensemble. On this site we will present events taking place in the project, whereas more in-depth presentations will be published in other forums.

Art work by Jenny Soep


One of the central ambitions of the project is to design musical experiments as a method for creating “productive disorder”, in order to explore the resulting forms of self-organization and complexity. From a musician’s point of view, disordering is a useful description of how we might experience what we are often doing in collective improvisation: playfully tweaking, shifting, fragmenting, displacing, clashing, inserting, dissolving, scattering, making irregular or asymmetric, etc. These actions somehow disrupt or transform the orderliness of the musical materials at hand, so that something happens where we have less control, which in turn yields more possibilities for reciprocal interaction. Importantly, disordering is not seen as the destruction of order (cf. Grosz 2008) but rather produces a complex combination of orders. When several non-coordinated patterns are working in tension against each other, this may be rewarding precisely due to the interpretational depth thus offered; musicians (and listeners) must then be active in choosing how and when to relate things to each other. Disorder(ing) is thus an important concept, precisely for the purpose of counteracting the idea of a pre-conceived form of order, or set of laws, that music has to adhere to in order to “make sense”.
        We experiment with various ways in which reciprocal interaction can take place not only between musicians, machines and electronics, but also with structural interrelations between musical materials. Using a modular approach we explore how musical/noisy materials can be (re-)combined in various ways. This has close affinities with African and African American musics, “in which the structural content of music is located in the free play of smaller constituent units. […] Thus, large-scale musical form emerges from an improvisatory treatment of these short-range musical ingredients” (Iyer 2004). In our work we develop a process-oriented approach and distinguish between different kinds of modules (“seeds”, “bundles” and “blocks”) while exploring how they can be connected and transformed. This involves processes such as permeability” (Ligeti 1965) and “morphability”; superimposition and amalgamation; role-taking and transitions (Nunn 1998). The modules consistently undergo variations (within and between performances) and serve as virtual diagrams for “rhizomatic connectivity” (Deleuze & Guattari 1993). In this work we draw upon studies on spectromorphology and interstructural relations of sound-configurations (Tenney 1961, Smalley 1997, Thoresen 2007), as well as using machines that introduce randomization, audio synthesis and algorithmic generation.
        In light of the above, our focus is on exploring when and how improvisation becomes markedly collective, not simply in the sense of “improvising together” but more specifically when something emerges in a way that goes beyond the individual’s ability to fully predict or grasp the influence of his or her contributions in relation to the whole, as well as how other’s contributions affect his or her own playing. This involves relationships between power and domination (Bell 2014): How can we powerfully affect each other without dominating? And what methods, techniques, compositions, materials or circumstances enhance the mutual reinforcement of power in collective improvisation?
        Another important ambition is to strive for a cross-fertilization between theory and practice. On the one hand, this involves exploring how artistic experiences of disorder and non-control might influence how we understand and value those parameters in a wider variety of situations. In this way, the project aims to contribute to a deeper understanding of collective and playful creative processes. On the other hand, by drawing from inspirational resources such as complexity theory and Deleuzian philosophy, we wish to create new methods for collective improvisation, and also to problematize terms and concepts in common use around improvisation that can often be controversial, such as “idiom”, “freedom” and “innovation” (especially in the light of nomadic ethics [Braidotti 2012]). We focus first and foremost on music and the artistic practice at hand, but illuminate discussion and reflection as an important resource for musical creativity and collaboration. This is also valuable for making the ethos that is involved in our work visible, and possibly for producing a transformed ethos.
        Finally, an important aspect is to document our working process for others, thus illuminating it for those outside our work. We wish to draw upon the broad and divergent spectrum of interests, backgrounds and approaches amongst both the four primary researchers in the group and the extended community of musicians with whom we collaborate, in order to enhance a polyphony of orders drawn from the disorder of different ways of playing, listening and conceiving of improvised music.
