All About Digital Music Formats
Therefore, we have collectively gathered a list of the main formats and invite you to come and share our knowledge and expertise.
I) Notation Software Formats
If Sibelius and Finale are the most established notation software on the market right now, Dorico is the exciting new kid on the block. Launched in 2016 and crafted by the original team behind the development of Sibelius, Dorico is owned by Steinberg Media Technologies. Dorico has an incredibly comprehensive and elaborate software with a great potential to dominate the market in the coming years.
Musescore is a free notation software and online community where musicians can share their creations.
Recently, promising iOS notation apps such as Symphony Pro and MusicJot have started to appear on the market. They still can’t compete with computer software but are a good solution for musicians looking for a mobile solution.
All of these native formats either export the composition as exchange formats such as MusicXML or graphic formats such as PDF or images.
II) Exchange Formats
- MusicXML (Music Extensible Markup Language) – .xml / .musicxml
The Music Extensible Markup Language is the recommended format for sharing sheet music between different software. It is read and write supported in more than 230 software/apps.
- Compressed MusicXML – .mxml.
Creates smaller files than the regular MusicXML. This is a newer standard and isn’t as widely supported by older score writers.
- MIDI (Musical Instrument Digital Interface) – .mid / .midi / .kar
The MIDI (Musical Instrument Digital Interface) format is compatible with virtually any sequencer, notation software, but is also used to control hardware instruments (especially synthesizers).
MIDI does not contain any audio information, but rather transmits data (pitch, velocity, note length, etc …) about how a specific sequence should be interpreted by the receiving software/instrument. The MIDI file is then interpreted by the audio rendering engine of the software/instrument, so the results might differ depending on the quality of the audio engine of the software you are using, as well as its specific sets of rules regarding display and pagination for instance.
Although LilyPond and MEI are also considered as universal formats, they are not compatible with the main notation software; therefore, we did not take them into account.
III) Graphic Formats
PDF (Portable Document Format)
We highly recommend using PDF (Portable Document Format) for viewing, distributing and printing sheet music scores and parts.
Here’s why:
- PDF is the only graphic format that can contain multiple pages.
- It integrates various types of content — text, images and vector graphics.
- It displays the exact same content and layout no matter which operating system, device or software application it is viewed on.
- Most users have a PDF viewer on their computer/mobile device, so extra software won’t be required to open it. Some of the PDF viewers generally found on most computer are: Safari, Firefox, Google Chrome, Preview, Adobe Reader, Evince and Microsoft Reader.
- PDF can easily be edited with PDF editors such as Adobe Acrobat Pro.
However, despite all its advantages, PDF has one major flaw. Once a music score has been exported as a PDF, it can’t be re-imported into a notation software for deep editing.
Development of optical music recognition (OMR) techniques aim to bridge that gap and make PDF editable, but when it comes to complex systems the results are far from perfect.
PDF Exported From A Notation Software:
PDF export from Sibelius
PDF Generated From A Scan:
Scanned PDF
- The scanned version will blur and pixelate if enlarged, whereas the exported PDF is vector based. This means that users can zoom unlimitedly without losing quality.
- The exported PDF is much lighter than the scanned version.
Pictures
All other graphic formats are mainly used to export a graphic section/area within the score (a symbol, bar, system, page, etc.), similar to taking a screenshot or a picture. These formats don’t allow users to manage multiple pages.
The main ones are:
- JPEG – .jpeg
JPEG (Joint Photographic Experts Group) applies lossy compression to images, which significantly reduces file size and quality. It’s important to keep in mind that the compression ratio can be adjusted allowing users to choose their desired quality level. - PNG – .png
PNG Portable Network Graphics) is lossless. It uses surface recognition to compress images. In other words, a black square shape – which in reality consists of many dark pixels with different intensity values –will be encoded as a black square of set dimensions, without picking up on every single different pixel. As a result, the file size will be significantly smaller than JPEG. - TIFF – .Tiff
Of all the graphic formats, TIFF (Tagged Image File Format) produces the largest and highest quality images, by preserving all their original characteristics. However a TIFF file sizes are very large and therefore more difficult to share.
Digital Music Format-Table
| FORMAT | ADVANTAGES | DISADVANTAGES |
|---|---|---|
| NOTATION SOFTWARE | Preserves all the music information and score layout, and is editable | N/A |
| MUSICXML | Can be shared from one software to another while preserving a maximum amount of information | Doesn’t preserve the score layout |
| Easy to view, distribute and print | Doesn’t allow users to make hard edits of the score content | |
| JPEG | Ideal for photos & covers | Loss of quality |
| PNG | Ideal for monochrome pictures | Less useful for photos & covers |
| TIFF | Great for Photoshop edition | Files are too heavy to easily share and send |
