ABC software is available for all platforms on either a freeware or shareware basis. ABCs were invented by Chris Walshaw as an easy way of transcribing folk music. While evolving in countries as far apart as the UK, Germany, Sweden, Canada and the United States, Mr. Walshaw and the ABC community are working towards standardizing the language. Presently it is primarily used for notating and playing back traditional tunes such as jigs and reels but has been already been used to transcribe music from Japanese Koto to Scarlatti. Using ABC Programs Just as you don't have to write music in order to read it, you don't have to understand ABCs in order to use them.
Most programs support many tunes per file.
You don't need a particularly powerful computer to import 100 tunes with the click of a mouse. There are a few caveats. Files are tiny because the bare minimum amount of information is given. This means some formatting and playback details are defined by the user within his program preferences. Assumption of default values can cause surprises.
