Our verdict on Oh Sheet!
Oh Sheet! is an open-source AI music transcription application for musicians, learners, and developers who want to turn songs into playable piano sheet music. It accepts YouTube URLs, audio uploads, and MIDI files, then uses Spotify Basic Pitch for note transcription. The application supports web, iOS, Android, and macOS, giving it a broad platform footprint for an open-source piano-focused tool.
Its strongest feature is the complete path from source audio to an arranged piano part. Optional Demucs stem separation can help isolate musical material before transcription, while the two-hand arrangement assigns melody, bass, and harmony. Humanized playback adds timing, dynamics, pedal marks, and articulations, and the interactive notation viewer is paired with a piano-roll visualization. Outputs include PDF, MusicXML, and playable MIDI, which suits both printed practice material and digital editing workflows.
Oh Sheet! is most compelling for users who specifically want piano arrangements and value open-source software that can be run or extended. The project also documents a hosted/proprietary engraver component, so not every part of the workflow is open source. Its documented integration is TuneChat, while tablature is not part of the output focus. Choose it for multi-platform piano transcription with flexible input and export options; choose an alternative if guitar tablature, broader instrument-specific notation, or a wider documented integration ecosystem is central to the workflow.
