The GUIDO Music Notation Format is a formal language for score level music representation. It is a plain-text, i.e. readable and platform independent format capable of representing all information contained in conventional musical scores. The basic GUIDO Format is very flexible and can be easily extended and adapted to capture a wide variety of musical features beyond conventional musical notation (CMN). The GUIDO design is strongly influenced by the objective to facilitate an adequate representation of musical material, from tiny motives up to complex symphonic scores. GUIDO is a general purpose musical notation format; the intended range of application includes notation software, compositional and analytical systems and tools, performance systems, and large musical databases.

Recordare has developed MusicXML™ technology to create an Internet-friendly method of publishing musical scores, enabling musicians and music fans to get more out of their online music. MusicXML 2.0 files will soon serve the same role for interactive sheet music that MP3 files serve for recorded music.
