The Brazilian Symposium on Computer Music (SBCM) are thriving and exciting venues for sharing ideas about recent developments in computer music, sound and music processing, music information retrieval, computational musicology, multimedia performance, and many other topics related to art, science, and technology. In 2021, the 18th SBCM will be hosted by the Federal University of Pernambuco (UFPE) and will be a fully online event at affordable prices to welcome a broad music technology audience. We aim to achieve a more extensive diversity of themes, aesthetic trends, markets, and communities.

The organizing committee welcomes the following contributions formats:

- Technical Papers, expected to present original research work, deal with research and outcomes involving subjects related to computer music's broad territory. Full technical papers will be presented at the scientific track. At least one of the authors must register for the conference. They can have up to 8 pages and must be written in English. Technical Paper reviews will be double-blind.

- Music Papers, centered on artistic and musical activities related to the conference theme, discussing artistic/creative processes description, aesthetics on digital music, computational musicology, or practice-based research approaches. These will be presented at the scientific track, and at least one of the authors must register for the conference. They can have up to 8 pages, must be written in English, and reviews will be single-blind.

- Short Papers can present either original or ongoing research, with a technical or musical focus within computer music topics. Short papers will be presented at the ENCM track, can have up to 4 pages, and can be written either in English, Portuguese, or Spanish. Reviews will be single-blind.

- Technical demos can showcase recent industrial developments and applications, which are not necessarily scientifically focused but are relevant to the computer music community. They will be presented at the ENCM. The organizing committee will curate these.

- Hands-on Workshops, Tutorials, and Short Courses are events in which tutors can instruct other participants on either basic computer music-related or novel, state-of-the-art topics. These events will be part of the ENCM and will be evaluated by the organizing committee.

- Reports for research groups, art collectives, studio practice presenting the artistic and research activity in a laboratory, project, research team, art collective, art groups, and/or any other kind of group work developed at Universities, communities, and Research Centers focused in computers and music. These will be presented at the ENCM event and can be either in English, Portuguese, or Spanish. The organizing committee will evaluate these.

- Performances and artworks to be presented in the Festival, comprising installations, telematic performances, videos, interactive artworks centered on the boundaries between computers, music, and possibly other forms of art and technology. The participants will present the works in formats that are feasible to be accessed remotely. These will be selected and organized by the organizing committee.
