Contest “21 Days with PianoRoll” Motiviation: The contest aims to help participants develop the habit of regular piano practice by promoting diversity in the performance of pieces. To succeed, participants must post daily for 21 consecutive days on our platform. How to Post: Record everything you play and create PianoRoll posts! Every note counts - you can score points practising scales, reading new material, playing through your repertoire or drifting into endless improvisations. Recordings you post can contain anything you would play to improve! Right now the only requirement is to record in MIDI format (sorry if you can’t!). You can record yourself with any MIDI recording software, or record your live session using the MIDI recording feature available on the platform. Evaluation Criteria: The evaluation will be based on the regularity of posts, creativity, difficulty level of the piece, quality of performance, and its artistic value. Note that our advanced algorithm can detect plagiarism, so all submitted recordings must be original. Prizes: 1000$ I Category and 200$ II Category Announcement of Results: The contest results will be announced on the 26th of November, 2024 at 6PM UTC on our platform and through our communication channels. Community: You can connect with the organizers and other contestants on our Discord server.
