Thanks MMario. It seems rather more limited than abc but covers the basics. For reference, the current abc draft is at http://www.gre.ac.uk/~c.walshaw/abc/abc-draft.txt

I don't know if any one is interested but some of this thread illustrates some of the difficulties we are trying to work through with abc.

Genie, quality graphics take up quite a bit of space and are only useful to those who can read music. In spite of problems, it is much better to try to use "computer readable" notation which can be manipulated and used to produce other output.

An area we are working on at folkinfo is producing reasonable sheet music from abc. For an example try try this. Clicking on the "txt" link (in the tune section) will show the abc used and (assuming you can view pdf files), following the "pdf" link will give you the sheet music. The sheet music is not stored on the site but is produced by running conversion routines on demand.
