This reflective case study sought to identify self-regulation processes associated with daily music practice, focusing on the researcher-performer perspective. The first author of this article is also the study participant: a classical guitarist and graduate student at a South-American University who took part in the Instagram challenge #100daysofpractice, which involves recording and posting a video of one’s daily musical practice for 100 uninterrupted days. Using analytic autoethnography as a self-reflective descriptive tool, the research explored self-regulated learning strategies and the impact of social media on music practice. By highlighting the processes and strategies employed during the challenge according to the six psychological dimensions of Self-Regulated Learning, the results suggest that these processes and strategies can be associated with more than one dimension.
