This paper explores participatory and socially engaged practices in ubiquitous music (ubimus). We discuss recent advances that target timbre as their focus while incorporating semantic strategies for knowledge transfer among participants. Creative Semantic Anchoring (ASC from the original in Portuguese) is a creative-action metaphor that shows promising preliminary results in collaborative asynchronous activities. Given its grounding in local resources and its support for explicit knowledge, ASC features a good potential to boost socially distributed knowledge. We discuss three strategies that consolidate and expand this approach within ubiquitous music and propose the label Radical ASC. We investigate the implications of this framework through the analysis of two artistic projects: Atravessamentos and Ntrallazzu.

This paper aims to expand the research on ecological synthesis models (KELLER, 1999) through the inclu- sion of improvisation practice. We propose a formalization of creative processes in sonic improvisatory-compositio- nal environments (targeting comprovisation), based on ecologically grounded creative practices. Our approach en- tails the use of socio-ecological models that deal with complex adaptive systems [SIBERTIN et al., 2011]. We develo- ped a performance/experiment called The Maxwell Demon, as a case study. The observations done during the study indicate that imitation is an important strategy for creative activities in socio-ecological systems. Improvisation may provide a relevant sonic content in ecological environments, enhancing their flexibility without losing consistency.

Part of the recent developments in Ubiquitous Music (ubimus) research involve the proposal of the Internet of Musical Stuff (IoMuSt) as an expansion and complement to the Internet of Musical Things (IoMusT). The transition from IoMusT to IoMuSt entails a critique of blockchain and non-fungible tokens (NFTs) as technologies for allotment, disciplination and regimentation of formerly open and freely accessible artistic web content. In brief, the replacement of the operative concepts constructed around “things” with strategies based on “stuff” highlights the underlying interconnected processes and factors that impact interaction and usage, pointing to resources that become disposable and valueless within an objectified and monetized musical internet. This conceptual and methodological turn allows us to deal with distributed-creativity phenomena in marginalized spaces, highlighting the role of resources that are widely reproducible, fluid and ever-changing. In this paper, we address IoMuSt-based responses to issues such as the artificial production of scarcity associated with the application of NFTs. The selected musical examples showcase the meshwork of dynamic relationships that characterizes ubimus research. In particular, we focus on a comprovisation project involving VOIP visual communication through Skype, Meet and Zoom, a ubimus experience involving a Telegram chatbot and a set of musical experiments enabled by an online tool for remote live patching.
