MP3 to sheet music
Convert your MP3 to MIDI in Melody Lab, download the .mid file, then open it in external notation software such as MuseScore Studio. Review the notes and rhythm there before exporting a score. This website does not generate sheet music or PDF files.
One melody · one file · up to 25 MB and 3 minutes · audio stays in your browser
Two separate steps, two different outputs
An MP3 contains recorded sound. Our converter follows one pitch at a time and writes note events into a MIDI file. A notation editor then interprets those events as written pitches and durations. Importing is a starting point for editing, not a guarantee that the printed rhythm matches what a musician intended.
Use an isolated melody when possible. A full mix, chords or overlapping voices will not become separate instrumental parts here. If you want to convert MP3 into sheet music for an ensemble, this site's single-melody output does not supply that arrangement.
Our tested MP3 → MIDI → notation handoff
On September 24, 2026, we selected a synthetic MP3 melody in the live Melody Lab converter using desktop Chrome. This was a controlled example, not a commercial song. The page displayed a length of 6.40 seconds. After conversion, it reported 8 notes with a range of C4–A4 and showed “Conversion complete. Adjust filters, preview, or download.” We downloaded the resulting MIDI rather than constructing a replacement file.
You can repeat the browser portion with our MP3 test recording and compare the actual MIDI download. Choose the MP3 in the converter, select Convert to MIDI, inspect the note count, and download the .mid. Keep that file: reloading the converter clears its current audio and result.
For the second step, we imported that exact download into MuseScore Studio 4.7.5 locally with its command-line export option. It produced a native score file; a second local export produced the score image below. Both commands finished with exit code 0. This test used the desktop program's offline command line, not its website or a cloud upload. The menu instructions later on this page are separately sourced from its official handbook.
The imported score was in 4/4 and displayed a tempo of 120. It contained tied notes, including notes crossing a barline. Inspection of the saved score found 12 written note elements for the browser's 8 detected note events. A sustained MIDI event can be represented by several tied written notes; those counts describe different things. The image is the unedited import, not a cleaned-up arrangement.
What to check at the handoff
- First compare the converter's MIDI preview with your source melody. If the pitches are already wrong, changing the score layout will not fix them. Review the selected pitch range and filters in the converter before downloading another MIDI.
- Save the MIDI under a recognizable name. Our example used notation-sample.mid, keeping it distinct from notation-sample.mp3. Open the MIDI in your notation editor; the MP3 and MIDI are not interchangeable inputs for this workflow.
- Compare the imported rhythm with the recording. In our example, the pitch sequence was readable, but the tied notation needed musical review. Do not treat a successful import or a larger number of written noteheads as proof that transcription improved.
- Keep an unedited import alongside any corrected score. Our downloadable MIDI and test record with file hashes preserve the handoff input, so you can distinguish later notation edits from what the browser actually produced.
This simple sample demonstrates file compatibility and one rhythm-reading issue. It does not establish transcription accuracy for vocals, piano recordings or complete songs.
Open the MIDI and export a score in MuseScore
In MuseScore Studio, choose File → Open and select your downloaded .mid file. The official handbook lists MIDI among the formats it can import. Review the resulting score and save an editable copy on your computer. See MuseScore's opening and saving instructions.
When your edits are ready, choose File → Export, select PDF, and export from MuseScore. The official export guide describes the available formats. That PDF is created by the external notation software; Melody Lab's download remains MIDI.
Does MP3 to music notes include lyrics or piano parts?
No. This workflow does not recognize lyrics, assign left and right hands, separate instruments or create an ensemble score. You must edit or arrange those details in other software. Start with the melody you need, check the MIDI, and only then work on notation.
Does the recording leave my device?
Melody Lab processes your audio in the browser without uploading it. The site uses Google Analytics for visit statistics. Our notation test also ran locally. If you later choose another service, check that service's handling of files separately.
