about abc notation
What: abc notation is a system designed to notate music in plain text format. It was designed primarily for folk and traditional tunes of Western European origin (such as English, Irish and Scottish) which can be written on one stave in standard classical notation. However, it has been used for many other types of music and, for example, Steve Allen has coded Beethoven's Symphony No. 7, Movement 2 in abc!
When: Since its introduction at the end of 1993 it has become very popular: there now exist tens of thousands of tunes in abc, from a variety of online collections and many abc software tools (for Windows, Mac, Linux, iPhone and other platforms) which can read abc notation and either process it into staff notation or play it through the speakers of a computer.
Why: One of the most important aims of abc notation, and one that distinguishes it from most computer-based musical languages is that it is very concise and can be read easily by humans. In other words, with a little practice, it is possible to play a tune directly from the abc notation without having to process and print it out.
The resulting compactness - each tune is about the same size as a short paragraph of text - and clarity make it very easy to notate tunes. Consequently, it can be easily emailed or discussed online or, if you prefer, just scribbled down on the back of an envelope.
How: Visit the learn abc page to discover how to use abc notation.
Where: Just about everywhere - according to music-notation.info abc is "perhaps the most common music notation format on the internet" and is registered as an internet media (MIME) type. You can find more information about abc notation in a wide variety of places on the web - just google it. Here is a small selection of articles:

about abc notation research
Abc notation has been used in academic research for some time. Apart from extensive on-line resources, such as large scale collections of historical and contemporary tunes, which have been available since soon after the start of the internet, abc's very simple, direct encapsulation helps to facilitate musical analysis and manipulation.
In particular, in recent years this has made it an ideal format for automated music composition & music generation tools, particularly using machine learning technniques which find it relatively easy to scan large numbers of existing tunes, understand some of the composition conventions & paradigms, and produce something in the same idiom. Take a look at folkrnn.org, devised and implemented by Bob Sturm and Oded Ben-Tal, for a great example.
My own research in recent years has used abc notation resources to focus on two aspects of music information retrieval:
- enhancements for melodic similarity algorithms and, in particular, the use of multilevel representation and recursive local alignment;
- graph-based visualisation tools (TuneGraph & CorpusGraph), particularly aimed at allowing users of abcnotation.com to explore tune variants and similarities.
The ideas and technniques are described in the following academic conference papers (full details on my academic research pages):
- A Visual Exploration of Melodic Relationships within Traditional Music Collections (CorpusGraph), 2018
- Tune Classification Using Multilevel Recursive Local Alignment Algorithms, 2017
- Constructing Proximity Graphs to Explore Similarities in Large-scale Melodic Datasets (TuneGraph), 2016
- Multilevel Melodic Matching, 2015
- TuneGraph, an online visual tool for exploring melodic similarity, 2014 (now superseded by the 2016 paper "Constructing Proximity Graphs ...")
- A Statistical Analysis Of The Abc Music Notation Corpus: Exploring Duplication, 2014
The abc website has existed in various forms and at various locations since 1995. It moved to its new home at abcnotation.com in June 2009.
Although the statistics vary, as of July 2018 it lists around 90 abc-based programs (from sophisticated transcription software to smart iPhone apps) plus a massive resource of around 575,000 tunes from 170 websites, and has about 250,000 visitors a year from all over the world.

Chris Walshaw, the inventor of abc and the developer of this website, is a Principal Lecturer and Reader in Informatics in the Department of Computing & Information Systems at the University of Greenwich*, London.
He is also a musician playing English & French bagpipes, flutes, whistles and saxophone.
abc notation bring together his love of music and his profound appreciation of computing, and the web in particular, as a communication tool of great power.
If you want to find out more about Chris' musical ventures, come to a gig, or even buy a CD, then take a look at MoltenAmba (instrumental pyrotechnics ... folk, blues and all that jazz), Angles (folk-trance groove for bals and eurobops), the Climax Ceilidh Band (English ceilidh), The Duellists (now defunct, but with a hurdy-gurdy and bagpipe cult CD), or Zephyrus (for exquisite, mind-blowing bagpipe music).
