capella is a musical notation program or scorewriter developed by the German company capella-software AG (formerly WHC), running on Microsoft Windows[3] or corresponding emulators in other operating systems, like Wine on Linux[4] and others on Apple Macintosh. Capella requires to be activated after a trial period of 30 days. The publisher writes the name in lower case letters only. The program was initially created by Hartmut Ring, and is now maintained and developed by Bernd Jungmann.
Capella is one of the earliest computer programs for music notation and has a relatively moderate price compared with Finale or Sibelius, though up to version 7 it ran only on Windows. Capella claims to have 300,000 users for the music notation program and 120,000 for the OCR program. Digital sheet music in capella formats is available in various online music libraries, especially in German speaking areas. The German Protestant hymnalEvangelisches Gesangbuch has been digitized using capella software.
The current version is Capella Professional 8.0, which includes guitar chord notation ability, and guitar tab writing functions, in addition to the standard music notation tools. A capella start program is offered with several restrictions for a lower price. A free capella reader can display, print and play a capella score.
Data entry is possible via computer keyboard entirely, via mouse or in a combination with a MIDI keyboard. It is intended for multi staff scores like choir music, or orchestral music. Capella is a practically oriented application suited for amateur and professional musicians alike. It includes engraving as well as MIDI import and export.
capella can play back the score (the full score or an arbitrary selection of staves) via the computer's sound card, to MIDI devices or using VST modules. capella'scaptune module allows to select the output channels and to fine-tune the sounds.
Version 7 brought live voice extraction: one can switch between the view on the full score for the whole orchestra and the view on a selection of the staves of one or a group of instruments. On printing and exporting, only the voices being shown in the current view will be used. Specific instruction of individual voices can be marked as "only visible in extracted voice". Live voice extraction is also available in the free Reader program; in the limited version of the editor Capella start, such live voice extractions are not available for editing.
Version 7.1 introduced Unicode compatibility; UTF-8 is now the standard text encoding format.
Current features
The following modules are advertised for Capella 7 (February 2016):
capella
For the production of large complex music scores. Edit and arrange a score of voices/instruments in any number of pages of any number of staves per line, with multiple voice parts per stave. Playback with MIDI sound, import/export with other music software via MusicXML.
capella start
Cut-down version of capella with up to 4 staves per line, up to 2 voices per stave, and up to 100 bars.
Technicalities
The file format of capella evolved from a proprietary digital encoding (filename extension *.cap) to an open, XML text based format called CapXML with extension *.capx. There are CapXML 1.0 and 2.0 formats. Each *.capx file is a ZIP archive containing the actual XML with filename score.xml. CapXML differs from MusicXML in various aspects, one being that in CapXML the basic node is the chord which can have one or more notes, whereas in MusicXML the notes of a chord are single nodes which have to be put into relation with one another.[5] Capella can import and export MusicXML files.
Documentation of CapXML and the binary CAP file format, as well as of the programming interface is available for download at the Capella website.
Capella provides a programming interface for Python scripts with a set of Python-classes providing the capella object hierarchy. Python scripts can be used as a plug-in to the capella program or run stand-alone, i.e. within a Capella editing session or externally, directly on the file or group of files. CapXML scores can, of course, be directly processed by any XML-aware software.
Capella-programmer Bernd Jungmann used the Python scripting to produce a Braille-interface to Capella for blind users with a refreshable Braille display. Braille printing is possible using the MakeBraille service of the German Central Library for the Blind (DZB - Deutsche Zentralbibliothek für Blinde) in Leipzig, which accepts CapXML and MusicXML files as input, and offers its service for private, non-commercial uses only.

History
Before capella, there was tonica, a program to analyse musical notation. Since some people used tonica mainly to print musical scores, the idea for a scorewriter was born.
The first version was published in 1992 as a program named "Allegro", running under MS-DOS with its own graphical interface. Since the name was already taken, the name had to be changed - taking the name from the brightest star in the constellation Auriga, Capella. Only the original file name extension ALL was kept for the binary notation file format. The first real capella is version 1.01 dated 15 May 1992. Version 1.5 was the last MS-DOS Version, published in 1993.
Version 2 used Windows 3.1. The file format changed to another proprietary binary format with extension CAP. Many details, including lyrics, were lost in the conversion from ALL to CAP files.
Version 3.0 moved from 16-bit to 32-bit software. The file format changed again, also with some losses in the conversion. This format is internally designated as CAP3. This binary file format was kept, until the XML-based format CapXML 1.0 with extension CAPX was introduced.
In 2004, scripting was introduced.
Capella has always used and uses copy protection; initially by requiring the installation CD to be in the CD reader, today by requiring activation (after a trial period of 30 days).
The company was originally called "whc Musiksoftware", then "whc Musiksoftware GmbH". The name was changed to "capella-software GmbH" in the fall of 2002, changing the legal form from GmbH to AG (Aktiengesellschaft) in March 2011.
Version 8, published in late 2017, is a major rewrite of the program using the Qt, a cross-platformapplication framework and widget toolkit, which made possible the publication of a version for macOS, i.e. Apple Macintosh. The Reader 8, using the Qt platform, had already been released March 29, 2016, 20 months before the main program.
LilyPond is a computer program and file format for music engraving. One of LilyPond's major goals is to produce scores that are engraved with traditional layout rules, reflecting the era when scores were engraved by hand.
Finale is a discontinued proprietary music notation software developed and released by MakeMusic for Microsoft Windows and macOS from 1988 until 2024, when it was discontinued.
A scorewriter, or music notation program is software for creating, editing and printing sheet music. A scorewriter is to music notation what a word processor is to text, in that they typically provide flexible editing and automatic layout, and produce high-quality printed results.
SCORE is a scorewriter program, written in FORTRAN for MS-DOS by Stanford University Professor Leland Smith (1925–2013) with a reputation for producing very high-quality results. It was widely used in engraving during the 1980s and 1990s and continues to have a small, dedicated following of engravers, many of whom hold the program in high regard due to its ability to position symbols precisely on the page. Several publications set using SCORE have earned Paul Revere and German Musikpresse engraving awards.
Braille music is a braille code that allows music to be notated using braille cells so music can be read by visually impaired musicians. The system was incepted by Louis Braille.
MusicXML is an XML-based file format for representing Western musical notation. The format is open, fully documented, and can be freely used under the W3C Community Final Specification Agreement.
Denemo is a scorewriter and music sequencer. Denemo has been under development since 1999.
Notation Interchange File Format (NIFF) is a music notation file format used primarily for transferring music notation between different scorewriters.
Music Write is a Windows-based music notation program created by Voyetra Music Software. It uses a MIDI-based system for storing events, and the most recent versions save music in MWK files, similar to Standard MIDI Files with additional text and symbol events. Currently, Voyetra offers three editions of Music Write: Starter Kit, Songwriter edition, and Maestro edition. All support printing, MIDI recording, and MIDI playback granted the user has the appropriate hardware.
NoteWorthy Composer (NWC) is a proprietary scorewriter application made by NoteWorthy Software. It is a graphical score editor for Microsoft Windows computers. Version 1 of NWC was released in October 1994, and Version 2 in September 2008.
Optical music recognition (OMR) is a field of research that investigates how to computationally read musical notation in documents. The goal of OMR is to teach the computer to read and interpret sheet music and produce a machine-readable version of the written music score. Once captured digitally, the music can be saved in commonly used file formats, e.g. MIDI and MusicXML . In the past it has, misleadingly, also been called "music optical character recognition". Due to significant differences, this term should no longer be used.
Mosaic was a Macintosh scorewriter application for producing music notation, developed by Mark of the Unicorn.
Mozart the music processor is a proprietary WYSIWYG scorewriter program for Microsoft Windows. It is used to create and edit Western musical notation to create and print sheet music, and to play it via MIDI.
MuseScore Studio is a free and open-source music notation program for Windows, macOS, and Linux under the Muse Group, which owns the associated online score-sharing platform MuseScore.com and a freemium mobile score viewer and playback app.
Overture is a music notation (scorewriter) program for Windows and Macintosh platforms, published and developed by Sonic Scores. While Overture is primarily a scorewriter program, it also allows editing the score's MIDI audio playback data in the manner of sequencer and digital audio workstation (DAW) software.
This is a comparison of music notation programs.
MusicEase is a WYSIWYG scorewriter created by Gary Rader and produced by MusicEase Software. It enables computers using Microsoft Windows and macOS to produce musical notation and listen to them in MIDI.
