Guido is a formal language for score level music representation. It is a plain-text format and can represent virtually all the
information contained in a musical score. The main home page for GUIDO is www.salieri.org/GUIDO
which includes links to the GUIDO NoteServer, documentation on the Basic Guido specification, and code for GUIDO implementations.
The Advanced GUIDO specification is still being developed, but its current state is included here for reference. Please note that modifications
to the specification are ongoing.
