A MusicXML Viewer lets musicians, composers, singers, arrangers, music teachers, and students open digital sheet music directly in a web browser. Upload a compatible MusicXML, XML, or MXL file to render the musical notation without needing to open the score in a full desktop notation program.

MusicXML is different from an audio format such as MP3 or WAV. Instead of storing a recording of a performance, MusicXML stores structured musical notation data.

Depending on the score, that data can include notes, rests, pitches, rhythms, measures, clefs, key signatures, time signatures, lyrics, dynamics, articulations, instrument parts, tempo markings, and other notation information.

This makes MusicXML particularly useful for transferring editable sheet music between different music notation programs.

MusicXML vs. MXL

You may encounter several related file extensions.

A .musicxml file contains standard MusicXML notation data. Some programs also save MusicXML using the more general .xml extension.

An .mxl file is compressed MusicXML. Compression can make larger scores more convenient to store and transfer while preserving the underlying notation information.

This viewer supports all three formats.

Viewing Your Sheet Music

Choose a MusicXML file from your device and the tool will attempt to render it as traditional sheet music.

Once the score is loaded, you can zoom in or out to make the notation easier to read. This can be useful when studying dense arrangements, chord voicings, lyrics, instrumental parts, or small notation details.

The original file remains unchanged by the viewer.

Why Can MusicXML Look Different Between Programs?

MusicXML is designed to exchange musical information between notation applications, but different programs can interpret engraving and layout instructions differently.

The same score may therefore have slightly different spacing, line breaks, page breaks, fonts, stem positions, text placement, or other engraving details when opened in different software.

Complex notation or features that are specific to the program that created the score may also not transfer perfectly.

For that reason, MusicXML is excellent for exchanging editable musical information, but it should not always be expected to preserve a score's appearance as precisely as a PDF.

MusicXML vs. MIDI

MusicXML and MIDI can both represent musical information, but they serve different purposes.

MIDI is primarily designed around musical performance information such as notes, timing, velocity, and instrument messages.

MusicXML is designed primarily around written music notation.

Because of this, MusicXML can contain notation details that are difficult or impossible to preserve accurately in a standard MIDI file.

For composers and arrangers who want to move an editable score between notation programs, MusicXML is often the more useful format.

Browser Compatibility

This viewer uses a browser-based sheet-music rendering engine to interpret the MusicXML data and draw the score. Very large or complicated scores may take longer to render, particularly on slower devices.

Support for unusual or highly specialized notation can also vary.

Tip: If a MusicXML score doesn't display correctly, try exporting the score again from the original notation program using its latest MusicXML or compressed MusicXML (MXL) export option. If preserving the exact visual appearance is more important than editing the notes, exporting a PDF from the original notation program may be the better choice.
