Some Wiki environments that have been adapted to use ABC are: Recently, ABC has been implemented as a means of composing and editing music in collaborative environments. More examples can be found on Chris Walshaw's ABC examples page, extensively displaying most ABC basic features, except rests, which would be denoted with z.

While abcm2ps software produces output that looks like: The following is an example of the use of ABC notation in MediaWiki.Īudio playback is not supported in your browser. Chris Walshaw has become involved again and is coordinating the effort to further improve and clarify the language, with plans for topics to be addressed in future versions to be known as ABC 2.2 and ABC 2.3 .

Īfter a surge of renewed interest in clarifying some ambiguities in the 2.0 draft and suggestions for new features, serious discussion of a new (and official) standard resumed in 2011, culminating in the release of ABC 2.1 as a new standard in late December 2011. Henrik Norbeck has also published a corresponding BNF specification. This specification is now maintained by Irwin Oppenheim. Guido Gonzato later compiled a new version of the specification and published a draft of version 2.0. Thereafter, Chris stepped away for several years from actively developing ABC. After much discussion on the ABC users mailing list, a draft standard (nominal version 1.7.6) was eventually produced in August 2000, but was never officially released. In 1999, Chris Walshaw started work on a new version of the ABC specification to standardize the extensions that had been developed in various third-party tools. In 2006 Phil Taylor reported that quite a few websites still serve ABC files as text/plain.

In 1997, Steve Allen registered the text/vnd.abc MIME media type with the Internet Assigned Numbers Authority (IANA), but registration as a top level MIME type would require a formal Request for Comments (RFC). In 1997, Henrik Norbeck published a Backus–Naur form (BNF).

It is a textual description of ABC syntax, cleaning up many of the ambiguities of the 2.0 Draft Standard, which, in turn, was grown from the 1996 User Guide of version 1.6 of Chris Walshaw's original 'abc2mtex'. The most recent standard for ABC was released 21 December 2011.

For more details see Chris Walshaw's short history of ABC and John Chambers's chronology of ABC notation and software. To reduce the tedium of writing the MusicTeX code, he wrote a front-end for generating the TeX commands, which by 1993 evolved into the abc2mtex program. Later he began using MusicTeX to notate French bagpipe music. In the 1980s Chris Walshaw began writing out fragments of folk / traditional tunes using letters to represent the notes before he learned standard Western music notation. History ĪBC notation was in widespread use in the teaching of Irish traditional music in the late 1970s and most probably much earlier than that. Later third-party software packages have provided direct output, bypassing the TeX typesetter, and have extended the syntax to support lyrics aligned with notes, multi-voice and multi-staff notation, tablature, and MIDI. Such software is readily available for most computer systems, including Microsoft Windows, Unix / Linux, Macintosh, Palm OS, and web-based. Even so, there are now many ABC notation software packages available that offer a wide variety of features, including the ability to read and process ABC notation into MIDI files and as standard 'dotted' notation. ĪBC notation being ASCII-based, any text editor can be used to create and edit the encoding. Originally designed to encode folk and traditional Western European tunes ( e.g., from England, Ireland, and Scotland) which are typically single-voice melodies that can be written in standard notation on a single staff line, the extensions by Walshaw and others has opened this up with an increased list of characters and headers in a syntax that can also support metadata for each tune. The earlier ABC notation was built on, standardized, and changed by Chris Walshaw to better fit the keyboard and an ASCII character set, with the help and input of others. This form of notation began from a combination of Helmholtz pitch notation and using ASCII characters to imitate standard musical notation (bar lines, tempo marks, etc.) that could facilitate the sharing of music online, and also added a new and simple language for software developers, not unlike other notations designed for ease, such as tablature and solfège. In basic form it uses the letter notation with a– g, A– G, and z, to represent the corresponding notes and rests, with other elements used to place added value on these – sharp, flat, raised or lowered octave, the note length, key, and ornamentation. ABC notation is a shorthand form of musical notation for computers.
