ABC notation
open-in-new
<h2 id="history">History</h2> <p>ABC notation was in widespread use in the teaching of Irish traditional music in the late 1970s and most probably much earlier than that. 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. Later he began using <a href="/facts/MusiXTeX/wN3Ly7C7">MusicTeX</a> to notate French bagpipe music. To reduce the tedium of writing the MusicTeX code, he wrote a front-end for generating the <a href="/facts/TeX/HDrl3Yvd">TeX</a> commands, which by 1993 evolved into the abc2mtex program.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> For more details see Chris Walshaw's short history of ABC<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> and John Chambers's chronology of ABC notation and software.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p> <h3>Standardization</h3> <p>The most recent standard for ABC was released 21 December 2011.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> It is a textual description of ABC syntax, cleaning up many of the ambiguities of the 2.0 <i>Draft Standard</i>, which, in turn, was grown from the 1996 <i>User Guide</i> of version 1.6 of Chris Walshaw's original <a href="http://abcnotation.com/abc2mtex/">"abc2mtex"</a>. program. In 1997, Henrik Norbeck published a <a href="/facts/Backus%25E2%2580%2593Naur_form/xbMXDntc">Backus–Naur form</a> (BNF).<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p><p>In 1997, Steve Allen registered the text/vnd.abc <a href="/facts/MIME/P8PDYuts">MIME</a> media type with the <a href="/facts/Internet_Assigned_Numbers_Authority/b6MlP6zQ">Internet Assigned Numbers Authority</a> (IANA),<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> but registration as a top level MIME type would require a formal <a href="/facts/Request_for_Comments/esftTvE7">Request for Comments</a> (RFC).<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> In 2006 Phil Taylor reported that quite a few websites still serve ABC files as text/plain.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> </p><p>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. 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.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> Thereafter, Chris stepped away for several years from actively developing ABC.<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> </p><p>Guido Gonzato later compiled a new version of the specification and published a draft of version 2.0. This specification is now maintained by Irwin Oppenheim. Henrik Norbeck has also published a corresponding BNF specification.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> </p><p>After 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. 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 . </p> <h2 id="example">Example</h2> <p>The following is an example of the use of ABC notation in <a href="/facts/MediaWiki/MbkLUTor">MediaWiki</a>. </p> <score lang="ABC"> Z:A de|ccAGE5d|c|!

TolCor T:|d]n L:1/8 </score> <p>Lines in the first part of the tune notation, beginning with a letter followed by a colon, indicate various aspects of the tune such as the index, when there is more than one tune in a file (X:), the title (T:), the time signature (M:), the default note length (L:), the type of tune (R:) and the key (K:). Lines following the key designation represent the tune. This example can be translated into traditional music notation using one of the ABC conversion tools. For example, the Score extension (using <a href="/facts/LilyPond/AILGy6Ie">LilyPond</a>'s abc2ly) code for the MediaWiki software renders this as: </p> Audio playback is not supported in your browser. You can download the audio file. <p>While abcm2ps software produces output that looks like: </p><p>More examples can be found on Chris Walshaw's ABC examples page,<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a> extensively displaying most ABC basic features, except rests, which would be denoted with z. </p> <h2 id="collaborative-abc">Collaborative ABC</h2> <p>Recently, ABC has been implemented as a means of composing and editing music in collaborative environments.
