This seems to be a very good document, covering not just V:, but a lot of other things as well. > > Corrections and additions are very welcome. > I have a minor correction >and (if the abc2ps family supported it) it would then display correctly in >those programs.

This explanation of octave= is not quite right. I suggest the re-wording Yaps and abc2midi support a simpler version of this, where the directive octave=-2 causes every note to be treated as having a pitch two octaves below the written pitch. The point being that it is not just drawing of the notes that is affected, but playing them too.
