Before
Imported MusicXML, MIDI, Jianpu, Score JSON, or a reviewed scan candidate.
Each feature page maps back to the same score project model rather than a separate one-off converter.

Real product example
One score, structured input and reusable output
Captured from the running score workspace after importing test MusicXML. Captured: Aug 29, 2026.

Selected event: E4 quarter note in the single reference measureDownload input case
Output
Corrected event: F-sharp4 quarter note with an accent in a separate revisionDownload output case
This deterministic download demonstrates one structured edit; selection, insertion, deletion, drag editing and properties operate on Score JSON.

Online notation creation
Use an online sheet music editor as a structured sheet music maker
Create and edit sheet music online from MusicXML, MIDI, Jianpu, a reviewed scan, or an existing score project. The music notation editor keeps notes, measures, parts, and revisions structured so you can extract parts, collaborate, transpose, play, and export the same score.
Workflow
How this path works
The public page leads into the authenticated app workflow when users are ready to process a score.
01
Import a structured score
Start from MusicXML, MIDI, Jianpu, Score JSON, or an OMR candidate promoted into an editable revision.
Corrections are stored as new Score JSON revisions so history can be restored without losing earlier versions.
Product detail
What to expect
Sheet music editor for OMR cleanup
Scanning is rarely perfect; this online music notation editor repairs recognition mistakes before playback, conversion, or export.
Structured music score maker
Create or correct notes with rendered-note selection, pitch and duration dragging, insertion, deletion, and property editing. Desktop-grade free-form engraving and full layout control remain in progress.
Collaborative sheet music editor Beta
Invite role-aware collaborators to a shared score with presence, conflict handling, and an offline change queue. Real-time collaboration remains a Beta workflow and should be tested before a large ensemble session.
Extract parts from a score Beta
Select one or more parts and split the full score into an independent practice project. Part copies preserve their source reference but do not yet follow later edits to the full score.
Edit MusicXML and scanned sheet music online
Import MusicXML directly or promote a reviewed scan into an editable revision, then correct notes, rhythm, key signatures, lyrics, and score markings in one browser workflow.
Common errors
Where this workflow usually fails
Trying to edit PDF pixels
Symptom: A scanned page looks editable, but the notes are still only an image.
How to fix it: Run recognition first or import MusicXML; the editor changes Score JSON and MusicXML, not pixels in a PDF.
Correcting notation without checking the source
Symptom: A plausible edit fixes one measure but changes the intended voice or rhythm.
How to fix it: Keep the source visible and validate the whole measure before saving a correction.
Expecting desktop engraving controls
Symptom: The musical data is editable but advanced page layout is not available.
How to fix it: Use this editor for structured correction and workflow continuity; finish specialized engraving in a compatible notation editor when needed.
Accuracy statement
What is reproducible and what needs judgment
Edits to structured notes are deterministic, but the editor cannot make an uncertain import correct by itself. MusicXML and MIDI can contain incomplete semantics, and OMR candidates can contain recognition errors. Accuracy therefore means preserving and validating the intended musical structure, not merely rendering a plausible page.
Test and review checklist
Compare the edited measure with the source or musical intent.
Play the changed passage and inspect voice timing.
Download and re-open MusicXML before publication or a high-stakes rehearsal.

Tradeoff
ScoreTransposer browser workflow
OMR cleanup, revision history, open-format export, and connected transposition/playback.
Advanced free-form engraving and page layout are still more limited than mature desktop suites.
Traditional notation editor
Deep engraving, layout, and composition from scratch.
Scan diagnostics and browser-based project continuity may require separate tools or file handoffs.
Scan-only OMR tool
Creating the first structured candidate.
It is not a replacement for measure-level correction and revision management.
FAQ
Questions about Online Sheet Music Editor
Practical limits and the expected workflow for this score tool.
What input does Online Sheet Music Editor accept?
Start from MusicXML, MIDI, Jianpu, Score JSON, or an OMR candidate promoted into an editable revision.
Can I edit the result after conversion?
Yes. Successful imports become Score JSON revisions that can be corrected, transposed, played, and exported from the score workspace.
What should I check before relying on the result?
Editing is built on Score JSON/MusicXML, not on PDF text or image pixels.
Can I create sheet music online with this editor?
Yes. The editor supports structured score creation and correction, including notes, rhythm, score properties, revisions, and part extraction. Advanced desktop-style engraving and unrestricted page layout are still in development.
