Abc (music notation)

abc, so capitalized by its inventor, Chris Walshaw, is a special-purpose programming language for creating musical notation, where melodies are represented in the ASCII character set by the letter which corresponds to each musical note. Because of the correspondence of letters and notes, abc notation tends to be learnable by musicians who are not necessarily computer programmers. Since the introduction of the first freeware compiler in 1993, the abc language has achieved widespread use for folk and traditional tunes which are typically single-voice melodies on a single staff. With multiple freeware compilers now available, the abc language continues to grow in popularity because it provides a cost-free alternative for creating musical scores, and because it provides a standard way for people to share tunes and scores on the world wide web. Although not held by any tranditional standards body, abc can be considered to be a de facto standard due to widespread, voluntary compliance by software authors to certain written specifications.

Arguably, the abc notation has revolutionized the learning of traditional and folk music, due to the proliferation of many thousands of tunes in this format throughout the Internet. Especially in Irish and Scottish traditional music, it is now possible to find "the abc" for all but the most obscure traditional tunes. This has also given people an easy and interesting way to discuss tunes online without the technical inconvenience of a recording of the tune. As a result, tune scholarship has arguably improved by the addition of such resources as The Fiddler's Companion by Andrew Kuntz; without the aggregating possibilities of the Internet, such resources would be difficult if not impossible to compile, and would in any case take much longer to compile.
