Digital sound synthesis and processing, music information representation and retrieval, computational creativity, languages and physical interfaces for music.
01 · Teaching
Computação Musical is the CIn/UFPE undergraduate course on sound, music and computers, taught by Geber Ramalho since 1999. Giordano Cabral taught three classes in it in 2009.1, before joining the Center's faculty (2009.1 syllabus); he began teaching it in 2015.1, with Geber Ramalho, and has led it since 2018. In 2025.2 he was teaching assistant to Filipe Calegário. The syllabus comes from the historical course description at www.cin.ufpe.br/~musica, in four blocks: fundamentals (sound, acoustics, psychoacoustics); processing and synthesis; symbolic representation and MIDI; music information indexing and retrieval. No musical background is required to take it.

Twelve editions: 2015.1, 2016.1, 2016.2 (Computação Musical 2), 2017.2, 2018.1 (with the graduate class, IN1132), 2019.1, 2020.1 (interrupted by the pandemic and resumed in 2021), 2020.3 (remote), 2021.1, 2021.2 (Computação Musical 2, IF760), 2022.1 and 2025.2 (IF754, with Filipe Calegário). Google Classroom holds eleven cards.
03 · Teaching
The course is organized around a project: each team builds a system that produces sound. The sequence repeats from edition to edition: presenting inspiring systems, ideation (inspiration cards, method 635, morphological box), group formation, project plan, technical submission with code, architecture and who did what, final submission with demonstration and 360 peer evaluation within the team. Guests from MusTIC and Daccord give talks and market feedback. In 2020.3 the eighteen videos of the course playlist were recorded and a curation of ninety pieces of content was gathered on Notion, used in later classes; in 2022.1 the course ran in three tracks — content, project and musical experience —, with quizzes prepared by the students themselves.

Fundamentals in March, then processing and synthesis with Matlab labs — with the spectrogram code and the sine- and sawtooth-wave generators made available to the class —, symbolic representation and MIR.
https://www.cin.ufpe.br/~musica/2015-1/Same syllabus as the previous offering: Matlab exercises, additive synthesis implemented using the class code, skeleton code for an LFO and a comb filter, Pure Data with João Tragtenberg, music information retrieval, and, in June, an open-book exam.
https://www.cin.ufpe.br/~musica/2016-1/Continuation class, with Filipe Calegário as co-instructor and João Tragtenberg on a teaching placement.
What remains from the semester is an August 2017 notice about a missed meeting and the invitation to a project launch at Portomídia.
In March the class brought in inspirations — Song Maker, Guitar Hero, Rocksmith, Reactable, Tenori-on, Web Audio API, trackers, game audio dev diaries —, then grouped on the board into categories: DAWs, learning, singing, AI (MIR, algorithmic composition), production, digital musical instruments and games.

In this class the course's video playlist was recorded — music theory, notation, MIDI, sound, acoustics, signals, storage, processing, synthesis, MIR — and the curation of materials on Notion was organized.
Class created in Classroom in September 2021, with no announcements, assignments, or materials folder; the teaching allocation for that semester does not include Computação Musical.
Hybrid class.
The edition ran in three parallel tracks.
